Does Drinking Milk at Night Help You Sleep

Almost every family has a version of this habit. A mother warms a glass of milk for a child who cannot sleep. An older person drinks a small cup before bed because that is what their own parents did. A tired worker comes home late, heats milk on the stove, and sits with it quietly before going to bed. The idea is old, simple, and passed down from one generation to the next: warm milk helps you sleep. But is it true, or is it only a comforting story? The honest answer sits somewhere in the middle. Milk does contain a few things that are connected with sleep, and the habit itself can help a person settle down at night. But milk is not a sleeping medicine, and a glass of milk will not fix sleep that is broken for other reasons, such as worry, late-night screens, caffeine, or a bedroom that is too hot. This article explains the simple story behind warm milk and sleep in plain words, so you can decide whether this old habit is worth keeping in your own evening routine.

Where the Warm Milk Idea Comes From

The warm milk habit is older than any modern sleep advice, and it grew up in homes where milk was a daily food and bedtime was a quiet time. In many parts of the world, milk was the last thing a child drank before bed, partly because it was nourishing and partly because it was warm and filling. A child who drank milk before bed was not going to bed hungry, and a child who was not hungry was more likely to fall asleep without fuss. Parents noticed this, and the habit became a rule in the house. Over time, the rule turned into a belief: milk itself makes you sleepy. The belief travelled from parents to children, from one country to another, and it is still alive today, long after the kitchens that started it have changed.

Books and films kept the idea going. In many stories, a kind grandmother brings a glass of warm milk to a child who is awake at night, and the child drifts off to sleep. That picture is powerful because it feels true, even if the milk itself is only a small part of the story. The grandmother, the quiet house, the warm drink, the feeling of being cared for: all of these together make a child feel safe, and feeling safe is one of the best conditions for sleep. The milk is the visible part of the ritual, so it gets the credit, while the comfort and the routine quietly do much of the work. This does not make the habit useless. It means the habit works for more than one reason, and understanding all of them helps you use it properly.

Doctors and researchers later tried to find out whether there was anything special in the milk itself, and they did find a few interesting things. Milk contains a substance called tryptophan, which the body uses to make serotonin and then melatonin, two chemicals that are involved in mood and sleep. Milk also contains calcium, which helps the body use tryptophan, and in small amounts, milk contains melatonin itself. These are real facts, and they give the old habit some support. But the amounts are small, and a single glass of milk is not the same as a medicine. The science says milk has ingredients that are connected with sleep, but it does not say that one glass will make a person fall asleep. That gap between the ingredient and the effect is where most of the confusion about warm milk comes from.

What Is Actually in a Glass of Milk

A glass of milk is a simple food, and that simplicity is part of its value. One glass of whole milk, about 200 millilitres, gives you roughly 120 to 150 calories, along with protein, calcium, vitamin B12, vitamin D in fortified milk, and small amounts of other vitamins and minerals. The protein in milk is useful because it slows down digestion, so a glass of milk keeps you feeling satisfied for longer than a glass of water or juice. The calcium is the nutrient milk is most famous for, and it supports bones and teeth, as well as helping muscles and nerves work normally. The fat in whole milk carries flavour and gives the milk its creamy feel, while low-fat milk has less fat and fewer calories but keeps most of the protein and calcium. For most people, either type works as a bedtime drink, and the choice is mostly a matter of taste and how much food you want before bed.

Tryptophan deserves a closer look, because it is the ingredient that is most often mentioned when people talk about milk and sleep. Tryptophan is an amino acid, which is one of the small building blocks that make up protein, and your body needs it to make serotonin, a chemical that affects mood, and melatonin, a chemical that helps your body know when it is time to sleep. A glass of milk contains about 100 milligrams of tryptophan, which is a modest amount. Foods like turkey, chicken, eggs and nuts contain more tryptophan per serving, but milk is still a reasonable source, and it is one of the few that people drink warm at bedtime. The body does not turn tryptophan into sleep in a straight line, though. It needs other things to happen first, including enough carbohydrate to help the tryptophan reach the brain, and a body that is already ready for sleep. A glass of milk on its own cannot force that process.

Milk also contains small amounts of melatonin, the hormone that rises in the evening and tells your body that night has come. The amount in milk is very small, far smaller than a supplement, and it varies depending on the time of day the milk was collected. Night milk, which is milk collected from cows at night, contains more melatonin than day milk, but this is still a small amount, and ordinary shop milk is not night milk. Calcium also plays a supporting role, because the body uses calcium in the process of making melatonin. None of this makes milk a sleep medicine. What it does mean is that milk is a sensible evening food, with ingredients that point in the right direction, rather than a food that works against sleep, like a strong coffee or a large sugary snack.

Why the Ritual Itself May Matter More Than the Milk

Here is the part of the warm milk story that is easy to miss: the habit may help you sleep even if the milk itself does very little. Sleep is not only about chemistry. It is also about routine, and your body learns from what you do every night. If you do the same calm things at the same time each evening, your body begins to expect sleep when those things happen. Warming milk, pouring it into a cup, sitting down quietly and drinking it slowly is a clear signal to your body that the day is ending. It is a pause between the noise of the day and the silence of the night, and that pause is valuable on its own.

Think about a person who comes home after a long day, checks their phone, watches the news, answers messages, and then lies down expecting to fall asleep in five minutes. Their mind is still running at full speed, and their body has had no signal that the day is over. Now think about the same person with a small bedtime ritual. They finish their work, they warm a glass of milk, they sit in a quiet room, they drink it slowly without a phone in their hand, and then they brush their teeth and go to bed. The second version gives the mind time to slow down. The milk is part of that slowing down, but so is the quiet, the warmth, and the absence of screens. If you replaced the milk with a warm glass of water or a small cup of herbal tea, the ritual would still work in much the same way, because the routine is doing a large share of the job.

Warmth matters too, and it matters in a simple, physical way. A warm drink raises the temperature of your hands and your stomach, and that feeling of warmth is relaxing. After drinking something warm, your body temperature slowly falls again as you settle into bed, and that fall in temperature is one of the signals your body uses to feel sleepy. This is the same reason a warm bath or shower before bed can help some people sleep: the warmth is followed by a gentle cooling, and the cooling feels like bedtime. A glass of warm milk gives you a small version of this effect, and it also gives your hands something warm to hold, which is comforting on a cold night. Cold milk does not give you the same feeling, which is why the old habit almost always calls for warm milk rather than cold.

What the Research Actually Says

If you are looking for a clear scientific answer, the honest truth is that the research on milk and sleep is thin and mixed. There are a few small studies that found people who drank milk before bed fell asleep a little faster or slept a little better, but these studies were small, short, and often looked at people who already had sleep problems. Other studies found no clear effect at all. There is no large, strong study that proves a glass of milk before bed makes healthy people sleep better, and there is no study that proves it does nothing. The science sits in the middle: milk has ingredients connected with sleep, the habit is harmless for most people, and some people feel it helps, but nobody can promise that it will work for you.

Part of the problem is that sleep is hard to study. A person’s sleep depends on many things at once: what they ate all day, how much they moved, how worried they are, how bright their room is, how hot the night is, and whether they drank tea or coffee late in the day. A study that only changes the milk and ignores all of these other things will get muddy results, because the other things are still changing the sleep. This is why you should be careful with strong claims about milk and sleep, in either direction. A person who tells you warm milk is a guaranteed cure for poor sleep is going too far. A person who tells you it is pure superstition is also going too far, because the ingredients and the ritual both have real, if modest, effects.

What the research does support clearly is the value of a light snack before bed for people who go to bed hungry. Hunger is a real reason for waking up at night, and a small snack that combines protein and a little carbohydrate can keep hunger away until morning. Milk fits that description well. A glass of milk is light enough not to sit heavily in the stomach, and it has enough protein and natural sugar to stop hunger. That is a practical benefit, and it may explain why so many people feel milk helps them sleep: it is not putting them to sleep, it is stopping hunger from waking them up. For a person who eats dinner early, at six or seven in the evening, and goes to bed at eleven, that five-hour gap is long, and a glass of milk at ten o’clock fills it gently.

When Warm Milk Can Make Sleep Worse

Warm milk is a gentle habit, but it is not right for everyone, and in some situations it can make the night worse instead of better. The clearest case is lactose intolerance, which is common in many adults. If your body does not make enough lactase, the enzyme that breaks down the sugar in milk, then a glass of milk before bed can cause bloating, wind, stomach pain, or a rush to the bathroom in the middle of the night. That is the opposite of good sleep. If you notice stomach discomfort after drinking milk, especially at night, it is worth trying a smaller amount, or a lactose-free milk, or skipping milk altogether and finding another bedtime drink. The point of the habit is to feel settled, and a drink that upsets your stomach cannot do that.

A second problem is size. A small glass of milk is a light snack. A very large glass, or milk with biscuits, cake, or a heavy snack on the side, is a late meal, and a late heavy meal can disturb sleep. When you lie down with a full stomach, the food can push back up into the throat, causing a burning feeling that keeps you awake. This is more likely if you drink the milk and go straight to bed. A good rule is to finish the milk at least half an hour before lying down, and to keep the portion small: one ordinary glass, not a jug. If you want something with the milk, keep it small too, such as one plain biscuit, rather than a plate of food.

A third problem is waking up to use the bathroom. Any liquid drunk late at night can make you wake up needing to go, and milk is no exception. If you already wake up once or twice a night, a full glass of milk just before bed may add another trip. Drinking the milk earlier in the evening, perhaps an hour before bed, gives your body time to process it, and keeping the glass modest in size helps too. Older people, who often wake more during the night anyway, should be especially careful with the timing and the amount. A small glass, drunk an hour before bed, is usually a better choice than a large glass drunk at the moment of lying down.

How to Try Warm Milk Properly for Two Weeks

If you want to find out whether warm milk helps you sleep, the best way is a simple, honest test over two weeks, changing nothing else at the same time. Start by choosing a time, about an hour before you plan to sleep, and keep it the same every night. Warm one small glass of milk, not too hot, so you can drink it slowly without burning your mouth. Sit somewhere quiet, away from your phone and television, and drink it slowly over ten minutes. Then brush your teeth and go to bed at your usual time. Do this every night for two weeks, and keep a short note each morning about how you slept: how long it took to fall asleep, how many times you woke up, and how rested you felt. A short line in a notebook is enough.

After two weeks, look at your notes and ask a plain question: did anything change? Some people find they fall asleep a little faster, or they wake up less hungry in the night. Others find nothing changed at all, and that is a useful answer too, because it tells you the habit is not the answer for your sleep, and you can stop spending time on it. The important part of the test is changing only one thing. If you start drinking warm milk and also stop using your phone at night, start exercising, and change your dinner time all in the same week, you will not know which change helped. One change at a time is slower, but it gives you a true answer, and a true answer is worth more than a quick guess.

If the milk test does not help, do not be discouraged. It does not mean your sleep cannot improve. It means milk is not the lever that moves your sleep, and the lever is probably somewhere else: the time you go to bed, the brightness of your room, the tea or coffee you drink late in the day, or the worry you carry into bed. Those are bigger levers, and they are worth looking at next. If the milk test does help, even a little, keep the habit, because a small improvement that costs almost nothing and does no harm is worth keeping. A habit does not need to be a miracle to be worth doing. It only needs to make your nights a little easier, night after night.

Milk at Night for Children, Adults and Older People

The warm milk habit looks different at different ages, and it is worth knowing how it fits each stage of life. For young children, warm milk before bed is one of the oldest and most common routines in the world, and it works well for many families. A small cup of warm milk gives a child food, warmth, and a clear signal that the day is ending, and children love routines. A child who knows that milk comes after the story and before the light goes out will settle more easily than a child whose evening has no pattern at all. The milk should be a small cup, not a bottle carried into bed, because milk left on the teeth overnight can damage them, and a child who drinks milk in bed may wake up wanting more. The routine matters more than the amount, and a calm, regular bedtime with a small cup of milk is a good pattern for most children.

For busy adults, the habit is often harder to keep, because evenings are full of work, messages, cooking, and chores. An adult who finishes work late may not want to cook or prepare anything, and a glass of milk is one of the few bedtime foods that needs almost no effort: warm it, drink it, and go to bed. That ease is a real advantage. An adult who is trying to sleep better often looks for complicated answers, but a simple habit that you can actually do every night is better than a perfect plan that you abandon after three days. For adults, the milk should be kept small, because a large glass late at night can feel heavy, and adults who are watching their weight should remember that a glass of whole milk is a real snack with real calories, not a free drink.

For older people, warm milk can be a comfort, especially on cold nights, and many older people have kept the habit for decades. But older people should also be careful about two things. The first is waking up at night to use the bathroom, which is more common with age, and a drink late at night can add to that. Drinking the milk earlier in the evening, and keeping the glass small, helps. The second is that older people sometimes take medicines at night, and a glass of milk can interfere with how some medicines are absorbed. This is general information, not advice about any particular medicine, but it is worth knowing: if you take medicine at night, ask your doctor or pharmacist whether milk at the same time is fine. A small gap between the medicine and the milk usually solves the problem, and it is a simple question worth asking.

Other Bedtime Drinks and Simple Habits That Help Sleep

Warm milk is not the only drink that can sit at the end of the day, and it is useful to know the alternatives, because milk does not suit everyone. A small cup of warm water with a little honey is a simple choice that gives warmth and a little sweetness without any milk at all. A cup of herbal tea, such as chamomile, is a common bedtime drink in many countries, and it works in the same way as milk: the warmth, the quiet, and the ritual do most of the work. Plain warm water on its own is the simplest option of all, and it suits people who do not want any food before bed. None of these drinks contains tryptophan or calcium in the way milk does, but they share the ritual value, and for many people the ritual is the part that matters most.

What you should avoid late at night is clearer than what you should drink. Strong tea and coffee contain caffeine, which keeps the mind alert and can delay sleep for hours, even in people who feel used to it. Sweet fizzy drinks give a rush of sugar and then a crash, and they can leave you thirsty. A large glass of juice is also mostly sugar, and it can wake you up with hunger or thirst in the middle of the night. Alcohol is often thought to help sleep, because it can make a person feel drowsy, but it disturbs the deeper parts of sleep and often causes waking in the early hours. If your evenings include any of these drinks late at night, changing them is likely to help your sleep more than adding a glass of milk. The best bedtime drink is a quiet one, and milk earns its place because it is quiet, warm, and light.

Beyond drinks, the habits around the milk matter as much as the milk itself. Going to bed at roughly the same time each night helps your body learn when to feel sleepy. Keeping the bedroom dark, cool, and quiet gives your body the conditions it needs. Putting the phone away an hour before bed removes the bright light and the stream of news and messages that keep the mind busy. None of these habits is difficult on its own, but together they make a large difference, and they are the reason sleep experts talk about a bedtime routine rather than a single food or drink. Warm milk fits into that routine as one small piece. It is a good piece, but it is not the whole routine, and expecting it to do the whole job alone will lead to disappointment. The people who get the most from warm milk are the people who use it as the quiet end of a calm evening, not as a quick fix after a loud and busy one.

My Take:

If you ask me whether drinking milk at night helps you sleep, my honest answer is that it can help, but not in the way most people think. I do not believe a glass of milk is a sleeping medicine, and I do not believe it will put you to sleep on its own. What I do believe is that milk is a good, gentle, sensible part of a calm evening, and that a calm evening is one of the best things you can give your sleep. The milk brings a little protein, a little calcium, a little tryptophan, and a little warmth. The ritual brings quiet, a pause, and a clear signal that the day is over. Put together, those small things add up to something real, and for many people, something real is enough. I would not promise a miracle, but I would not dismiss the habit either. It sits in the honest middle, and the honest middle is where most useful health habits live.

I think the reason this habit has lasted so long is that it asks almost nothing of you. You do not need to buy anything special, you do not need to learn a new skill, and you do not need to change your whole life. You warm a glass of milk, you sit down, you drink it slowly, and you go to bed. That simplicity is a strength, because the habits that last are the ones that fit into a real evening. I have seen many sleep plans that look perfect on paper and fail in real life because they ask too much: a special pillow, a special light, a special routine that takes an hour. Warm milk is the opposite of that. It is a small habit that a tired person can actually do, and a habit you actually do is worth far more than a perfect plan you abandon after three days. That is my first reason for liking it.

My second reason is about hunger, because I think hunger is an underrated cause of broken sleep. Many people eat dinner early, at six or seven in the evening, and then go to bed at eleven, and they wonder why they wake up at two in the morning feeling restless. A glass of milk at ten o’clock is a quiet answer to that problem. It is not a meal, it is not heavy, and it will not sit in your stomach like a stone, but it gives your body enough protein and energy to last until morning. I think a lot of the people who say warm milk helps them sleep are really saying that it stops hunger from waking them up, and that is a perfectly good reason to keep the habit. It is not magic. It is a small snack at the right time, and small snacks at the right time are useful.

I also want to be honest about what milk cannot do, because I think exaggerated claims help nobody. A glass of milk will not fix sleep that is broken by worry, by a phone glowing in a dark room, by strong tea at nine o’clock, or by a bedroom that is too hot. If those things are wrong, the milk is a small bandage on a bigger problem, and the bigger problem will keep waking you up. I would rather say this plainly than let someone drink milk for a month and wonder why nothing changed. Sleep is a whole pattern, not a single drink, and the person who fixes the pattern will sleep better than the person who only adds the milk. That does not make milk useless. It makes milk one piece of a bigger picture, and I think it is better to know that than to expect too much from one glass.

There is another reason I like the warm milk habit, and it is about children. I think a small cup of warm milk before bed is one of the kindest routines a parent can give a child, not because of the tryptophan or the calcium, but because of what the routine teaches. A child who has a calm bedtime, with a warm drink, a quiet room, and a parent who is not rushing, learns that the end of the day is safe and peaceful. That lesson stays with them. Children who grow up with calm evenings often become adults who protect their evenings, and adults who protect their evenings usually sleep better than adults who do not. A glass of milk is a small thing, but it can be the anchor of a routine that shapes a lifetime of sleep, and I think that is worth more than any single ingredient in the milk.

I also think we should be fair about the limits of the science here. I have read the claims on both sides: some people say the research proves milk helps you sleep, and others say the research proves it does nothing. In my view, neither side is telling the full story. The research is small, mixed, and hard to read, because sleep depends on so many things at once. What the research does show is that milk contains ingredients connected with sleep, that a light snack before bed can help people who go to bed hungry, and that a calm routine helps sleep. That is enough for me to say the habit is worth trying, and not enough for me to say it is guaranteed to work. I prefer this honest version, because when people expect a guarantee and do not get one, they stop trusting good advice altogether. A glass of milk is a good habit to try, not a promise.

If a friend asked me how to try it, I would keep the advice simple. Drink one small glass, warm, about an hour before bed, in a quiet room, without a phone in your hand. Do it every night for two weeks, and keep a short note each morning about how you slept. Then look at the notes and decide. If it helped, keep it. If it did not, stop, and look at the bigger things: your bedtime, your room, your evening drinks, and your worries. Do not add biscuits and cake to the milk, do not drink a huge glass and lie down straight away, and do not expect the milk to fix a week of late nights on its own. A small habit, done properly, is the only fair test, and a fair test is the only way to know whether something works for you.

I would also tell that friend to watch out for the two situations where milk is the wrong choice. If milk upsets your stomach, with bloating or pain or a rush to the bathroom, then warm milk before bed is not a comfort, it is a disturbance, and you should try something else, like warm water or a herbal tea. And if you take medicine at night, ask your doctor or pharmacist whether milk at the same time is fine, because milk can affect how some medicines work. These are not reasons to fear milk. They are reasons to use it with a little care, and a little care is part of any good habit. The best habits are the ones you choose with your eyes open, knowing both what they can do and where their limits are.

There is one more thing I want to say about cost, because I think it matters more than most health advice admits. Warm milk is one of the cheapest bedtime habits there is. A glass of milk costs very little, it is sold in every shop, and it needs no special product, no app, and no subscription. Compare that with the sleep products that are sold everywhere today: special pillows, special lights, special teas in expensive boxes, and powders that promise deep sleep. Most of those things cost far more and do far less than a quiet evening and a small glass of milk. I am not against spending money on sleep, but I think a person should start with the cheap, simple things first, and only spend money when the simple things have been tried properly. Milk is a good place to start because it is cheap enough that anyone can try it for two weeks without thinking about the price.

I also want to say something about what a fair test looks like, because I think many people test a habit badly and then blame the habit. A fair test means one change at a time, the same time every night, and an honest note in the morning. It does not mean drinking milk once, sleeping badly because the neighbour’s dog barked all night, and deciding milk does not work. Sleep has many causes, and one bad night proves nothing. Two weeks of notes, on the other hand, tells you something real. If your notes show that you fell asleep a little faster, or woke up less hungry, or simply felt calmer in the evenings, then the habit has earned its place. If your notes show nothing at all, then you have learned something too: milk is not your answer, and your time is better spent on the bigger levers. Either way, you have not wasted two weeks. You have learned how your own sleep works, and that knowledge is worth more than any single habit.

Another honest point is that milk is only one small part of the evening, and the other parts often matter more. A person who drinks warm milk and then scrolls through their phone in a bright room for an hour has undone most of the good the milk did. The bright light tells the brain that it is still daytime, and the stream of messages keeps the mind busy. A person who drinks strong tea at nine o’clock and then wonders why a glass of milk at eleven did not put them to sleep is asking the milk to fight a battle it cannot win. Caffeine stays in the body for hours, and no food can cancel it. If you want the milk to help, give it a fair chance: put the phone away, keep the tea for the morning, and let the evening be quiet. The milk is a helper, not a magician, and helpers work best when they are not fighting against you.

I also think there is a lesson here about old habits in general, and it is a lesson I want to leave with you. Old habits are not always right, but they are not always wrong either. The warm milk habit survived for generations because it was cheap, simple, and harmless, and because it was wrapped in a routine that helped people settle. Modern advice often throws away old habits without looking at them closely, and then sells a new version of the same idea in an expensive box. I would rather look at an old habit carefully, keep the parts that work, and drop the parts that do not. Warm milk is a good example of that. The idea that it contains a magic sleep chemical is too big a claim. The idea that it is a warm, light, protein-rich end to a calm evening is a fair one. Keep the fair version, and you will get the most from it.

So here is my final view, in plain words. Warm milk at night is a gentle, old, sensible habit. It will not put you to sleep like a medicine, but it can help you settle, it can stop hunger from waking you, and it can be the quiet end of a calm evening. Try it for two weeks, one small warm glass, an hour before bed, and see what your own nights tell you. If it helps, keep it, because a small habit that makes your nights a little easier is worth keeping. If it does not help, let it go without regret, and look at the bigger pieces of your sleep instead. In my view, that is the right way to treat an old habit: respect it, test it honestly, and keep it only if it earns its place in your evening.

Frequently Asked Questions

Is does drinking milk at night help you sleep something I should think about every day?

It is worth thinking about only if you drink milk at night or are considering starting the habit. For most people it is a small, harmless evening choice, not something to worry about daily. If milk helps you settle and stops hunger from waking you, it can become a simple nightly routine. If it upsets your stomach or makes you wake up to use the bathroom, it is not worth keeping. The daily question that matters more is whether your whole evening is calm: a regular bedtime, a dark room, and no strong tea or coffee late at night.

How long does it take to notice anything from does drinking milk at night help you sleep?

There is no fixed timetable, because milk is not a medicine. If it helps you, the most likely change is small: falling asleep a little more easily, or waking up less hungry in the night. Give it a fair test of about two weeks, with one small warm glass at the same time each evening, and keep a short note each morning about how you slept. Most people who notice anything notice it gradually over that first week or two, not after a single night. If nothing has changed after two weeks, milk is probably not the thing that will improve your sleep.

Can does drinking milk at night help you sleep fit into a busy workday?

Yes, easily, because the habit takes only a few minutes. Warming a glass of milk and drinking it slowly is one of the simplest bedtime routines there is, and it needs no special equipment or preparation. The harder part for a busy person is not the milk, it is finding ten quiet minutes in the evening. If your evenings are full of work and messages, the milk alone will not slow your mind down. It helps most when it is part of a short pause: milk, a quiet room, no phone, and then bed.

What is the simplest way to start with does drinking milk at night help you sleep?

The simplest start is one small glass of warm milk, drunk slowly about an hour before bed, every night for two weeks. Do not add biscuits or a heavy snack, do not drink a large glass, and do not lie down straight after drinking it. Keep everything else the same so you can tell whether the milk made a difference, and write one short line each morning about how you slept. After two weeks, look at your notes and decide whether to keep the habit or stop it.

Does does drinking milk at night help you sleep work the same way for everyone?

No, it does not work the same way for everyone. Some people find a warm glass of milk settles them and helps them sleep through the night, often because it stops hunger or because the quiet ritual calms them down. Others notice nothing at all. And some people find milk makes their sleep worse, usually because of lactose intolerance, a full stomach, or waking up to use the bathroom. Age, digestion, bedtime, and the rest of your evening all change how the habit feels, so the only honest answer is to try it yourself for two weeks and see.

What should I do if does drinking milk at night help you sleep does not suit me?

If milk does not suit you, stop drinking it at night and try something else. If milk upsets your stomach, try warm water or a small cup of herbal tea instead, and keep the same quiet routine. If the problem is waking up to use the bathroom, try drinking the milk earlier in the evening or making the glass smaller. If your sleep is still poor after two weeks without milk, look at the bigger things: your bedtime, your room, late caffeine, and worry.
