If you’ve just thrown up after drinking, the most important things right now are staying hydrated, positioning yourself safely, and letting your stomach settle. Vomiting is your body’s way of ejecting alcohol that’s irritating your stomach lining, but it also leaves you dehydrated and depleted. What you do in the next few hours matters for how quickly you recover and whether you stay safe.
Right After Vomiting: The First 30 Minutes
Don’t eat or drink anything immediately. Your stomach just forcefully expelled its contents, and the muscles around it are still irritated and contracting. Give yourself at least 15 to 30 minutes of rest before introducing any fluids. Trying to drink water right away often triggers another round of vomiting, which makes dehydration worse.
If you’re helping someone else who has vomited and is very intoxicated or losing consciousness, roll them onto their side into what’s called the recovery position. This keeps their airway open and lets any additional vomit drain out of the mouth instead of being inhaled into the lungs. When someone is unconscious, they lose the cough reflex that normally prevents choking. Aspiration, where vomit enters the lungs, is one of the most dangerous complications of heavy drinking.
Stay sitting upright or on your side. Don’t lie flat on your back.
Signs You Need Emergency Help
Vomiting after drinking is common, but certain signs point to alcohol overdose, which is a medical emergency. According to the National Institute on Alcohol Abuse and Alcoholism, call 911 if you or someone with you has any of the following:
- Slow breathing: fewer than 8 breaths per minute
- Irregular breathing: gaps of 10 seconds or more between breaths
- Mental confusion or stupor
- Inability to wake up or difficulty staying conscious
- Seizures
- Bluish or very pale skin, especially around the lips or fingertips
- Extremely low body temperature or clammy skin
- No gag reflex
Blood in your vomit is another red flag. Small streaks of pink or red can happen from the force of retching, but dark brown or bright red vomit in any significant amount means something more serious is going on and warrants medical attention.
How to Rehydrate Safely
Once 20 to 30 minutes have passed without further vomiting, start sipping water slowly. Take very small amounts, just a few sips every few minutes. Gulping a full glass will likely overwhelm your stomach and bring on more nausea. The goal is to replace what you lost gradually.
Alcohol is a diuretic, meaning it causes your kidneys to flush out more water than you’re taking in. Vomiting on top of that creates a significant fluid deficit. You’re also losing electrolytes, particularly sodium and potassium, which your muscles and brain need to function normally. This is a big part of why you feel so terrible.
Once plain water stays down, you can move to something with electrolytes. A sports drink diluted with water, coconut water, or a pediatric electrolyte solution all work. Broth is another good option because it provides sodium and is gentle on the stomach. Avoid anything carbonated, caffeinated, or acidic (like orange juice) for at least a few hours. Caffeine is also a diuretic, which works against your recovery.
When and What to Eat
Alcohol damages the stomach lining on contact. Within minutes of exposure, it triggers inflammation and increased blood flow to the stomach wall, essentially creating a mild chemical burn on the tissue. This is why your stomach still feels raw and sensitive even after you’ve stopped vomiting.
Wait until nausea has clearly passed before attempting food, which might be a few hours or even the next morning. When you do eat, start with bland, easy-to-digest options: plain toast, white rice, bananas, plain crackers, or applesauce. These foods are low in fat and fiber, which means your irritated stomach doesn’t have to work hard to process them.
Avoid spicy, greasy, acidic, or heavily processed foods for at least 24 hours. These will further irritate your already-inflamed stomach lining. Lean proteins like plain chicken or eggs can be introduced once bland foods are sitting well. Eating small amounts frequently is easier on your system than trying to have a full meal.
Pain Relief: What’s Safe and What’s Not
You’ll probably wake up with a headache, and your instinct will be to reach for a painkiller. Be careful with your choice. Acetaminophen (Tylenol) is processed by your liver, which is already busy breaking down alcohol. Taking it while alcohol is still in your system increases the risk of liver damage. As a general rule, avoid acetaminophen for at least 24 hours after heavy drinking.
Anti-inflammatory painkillers like ibuprofen (Advil) and aspirin are easier on the liver, but they irritate the stomach lining. Since alcohol has already inflamed your stomach, adding these on top can increase the risk of gastric bleeding, especially on an empty stomach. If you do take ibuprofen, eat something bland first and keep the dose low.
For many people, the best immediate approach is to skip the painkillers and focus on hydration and rest. Dehydration is the primary cause of that pounding headache, and fluids with electrolytes often do more for it than any pill.
Sleep and Monitoring
Sleep is one of the best things for recovery, but there are a few precautions. If you’re still actively intoxicated, sleep on your side rather than your back. Your blood alcohol level can continue to rise for up to an hour after your last drink, especially if you had a lot in a short period, so you can actually become more impaired after you stop drinking.
If you’re watching over someone who got sick from drinking, check on them periodically. Make sure they’re breathing normally, their skin color looks okay, and they respond when you shake their shoulder or call their name. Someone who vomited and then passed out is not “sleeping it off” in a safe way if they can’t be roused at all.
The Next 24 Hours
Your stomach lining needs time to heal. Most people feel noticeably better within 12 to 24 hours, though lingering nausea, fatigue, and general achiness can persist. Continue prioritizing fluids throughout the day. Your urine color is a simple guide: pale yellow means you’re adequately hydrated, while dark yellow or amber means you need more fluids.
Alcohol also depletes B vitamins, particularly B1 (thiamine), which plays a key role in brain and nerve function. For occasional heavy drinking episodes, eating a balanced meal with whole grains, eggs, or leafy greens the next day helps replenish what was lost. A standard multivitamin can also help fill the gap.
If nausea, stomach pain, or vomiting persists beyond 24 hours, or if you notice you can’t keep any fluids down at all, that’s a sign your body may need more help than home care can provide. Persistent vomiting creates a cycle of worsening dehydration that can become dangerous on its own, separate from the alcohol.
