If you’re vomiting from alcohol, the most important thing to do right now is stop drinking, sit upright, and take very small sips of water. Vomiting is your body’s protective response to too much alcohol in your system, and in most cases it will pass on its own within a few hours. Your job is to stay safe, stay hydrated, and let your stomach settle.
Why Alcohol Makes You Vomit
Alcohol directly irritates the lining of your stomach. Nerve endings in the stomach wall detect the irritation and send a signal to the brain that something harmful is present. At the same time, a region in the brainstem monitors alcohol levels in your blood. When those levels climb too high, the brain sends a signal back down to the stomach to expel its contents. This is a protective mechanism, not a malfunction. Your body is trying to prevent more alcohol from being absorbed.
This means you generally should not try to suppress vomiting with medication while you’re still intoxicated. Your body is doing exactly what it needs to do. The goal is to manage the discomfort and avoid complications, not to fight the reflex itself.
What to Do Right Now
Stop drinking immediately. Every additional sip adds more irritation and more alcohol to your blood. Sit upright or lean slightly forward. Do not lie flat on your back, because vomiting while lying down creates a choking risk.
Once the vomiting slows, begin sipping water in very small amounts. A few sips every five to ten minutes is enough to start. Gulping large quantities of water on an irritated stomach will likely trigger another round of vomiting. The key phrase to remember is calm, gradual hydration. If plain water is hard to keep down, try sucking on small ice chips instead.
Once you can tolerate water, move to drinks that replace electrolytes. Sports drinks, broth, or coconut water all work. Bananas, boiled potatoes, pickles, and natural yogurt are also good sources of sodium, potassium, and magnesium, the three electrolytes you lose most through vomiting and alcohol’s diuretic effect. Don’t rush this. If sipping water still makes you gag, wait another 15 to 20 minutes and try again.
What to Avoid While Your Stomach Recovers
Skip coffee and acidic drinks like orange juice. Caffeine is a diuretic that worsens dehydration, and acid on an already-irritated stomach lining will make nausea worse. Carbonated drinks can also increase the feeling of bloating and trigger more vomiting in some people, though others find flat ginger ale settles their stomach.
Be careful with pain relievers. Anti-inflammatory drugs like ibuprofen and aspirin can further irritate your stomach lining, which is already inflamed from the alcohol. Acetaminophen (Tylenol) puts extra strain on your liver at a time when your liver is already working hard to process alcohol. If you have a headache, hydration and rest are safer choices in the short term.
Eating After the Vomiting Stops
Once you’ve gone at least an hour or two without vomiting and you’re keeping fluids down, you can try eating. Stick to the BRAT approach: bananas, rice, applesauce, and toast. These foods are bland, high in simple carbohydrates, and easy for an irritated stomach to process. They also help stabilize blood sugar, which drops after heavy drinking and contributes to feeling shaky and weak.
Bananas pull double duty here because they’re rich in potassium, helping replace what you lost. Plain crackers, oatmeal, or a simple broth-based soup are also good early options. Avoid greasy, spicy, or heavy foods for at least several hours. Your stomach lining needs time to calm down before it can handle anything demanding.
How Long Recovery Takes
For a single episode of overdrinking, nausea and vomiting typically resolve within 4 to 12 hours as your body clears the alcohol. You’ll likely feel rough the next day, but the active vomiting should stop well before that. Staying hydrated shortens the miserable part significantly.
Your stomach lining is a different story. Even after you feel better, the gastric lining can remain irritated. With a one-time episode, it usually heals within a few days. But if heavy drinking is a regular pattern, the lining may take weeks or even months to fully recover, a condition called alcoholic gastritis. Repeated irritation makes each episode worse and lowers the threshold for vomiting the next time.
When Vomiting Becomes an Emergency
Most alcohol-related vomiting is unpleasant but not dangerous. However, alcohol poisoning is a medical emergency, and vomiting is one of its early signs. Call 911 if you or someone near you shows any of these symptoms alongside vomiting:
- Breathing changes: fewer than eight breaths per minute, or gaps longer than 10 seconds between breaths
- Confusion or unresponsiveness: difficulty staying conscious, inability to wake up, or severely slowed responses
- Seizures
- Skin color changes: skin that looks blue, gray, or unusually pale
- Low body temperature: skin feels cold and clammy
A person who has passed out from drinking and cannot be woken up could die. Alcohol poisoning suppresses the gag reflex, which means someone can vomit and choke without being able to clear their airway. If someone is unconscious, roll them onto their side (the recovery position) and stay with them until help arrives. Do not leave them alone to “sleep it off.”
Also seek medical attention if vomit contains blood or looks like dark coffee grounds, which can signal a tear or bleeding in the stomach lining.
Preventing It Next Time
The single most effective prevention strategy is eating a substantial meal before you drink. Food in the stomach slows the rate at which alcohol reaches the small intestine, where most absorption happens. This gives your liver more time to process each drink before the next one hits your bloodstream. The best pre-drinking meals contain a mix of protein, fat, and carbohydrates. Think a chicken sandwich, eggs and toast, or pasta with meat sauce. Fat slows digestion the most, which is why a meal with some oil or cheese works better than dry crackers alone.
Beyond food, pace matters. Your liver processes roughly one standard drink per hour. Spacing drinks out, alternating alcoholic drinks with water, and avoiding shots or drinking games all reduce the chance that alcohol builds up faster than your body can handle. Vomiting is your body’s last-resort signal that you’ve exceeded its capacity. If it keeps happening, the clearest fix is drinking less.
