If you keep throwing up after drinking, the most important things to do right now are stop drinking alcohol, take small sips of water or an electrolyte drink, and rest in a position where you won’t choke if you vomit again. Most alcohol-related vomiting resolves on its own within 24 hours, but there are specific steps that speed recovery and warning signs that mean you need emergency help.
Why Alcohol Makes You Vomit
Alcohol irritates and inflames your stomach lining by disrupting the protective mucus layer that normally shields it. This condition, called gastritis, triggers nausea, abdominal pain, and vomiting. The more you drink, the more damage that mucus layer takes, and the harder your stomach works to expel what’s irritating it.
On top of that, alcohol is a diuretic. It pushes fluids out through your kidneys faster than normal, depleting electrolytes like sodium and potassium along the way. Vomiting accelerates that fluid loss even further. This combination of stomach inflammation and dehydration is what makes you feel so terrible, and it’s why rehydration is the single most important part of recovery.
What to Do Right Now
Give your stomach a short break. For the first couple of hours after your last episode of vomiting, don’t try to eat or gulp down large amounts of water. Your stomach needs a grace period before it can handle anything.
Once you feel ready, start with small sips of clear liquids. Water, an electrolyte drink, or broth all work. The key word is “sips.” Drinking too much too fast will stretch your already-irritated stomach and likely trigger another round of vomiting. Take a few small sips every 10 to 15 minutes and gradually increase the amount as your stomach tolerates it.
If you’re lying down, stay on your side rather than your back. This prevents choking if you vomit while drowsy or asleep. Sleep as much as you can. Your body recovers faster when you’re resting, and fatigue makes nausea worse.
How to Rehydrate Effectively
Plain water helps, but it doesn’t replace the electrolytes you’ve lost through vomiting and alcohol’s diuretic effect. Sports drinks, oral rehydration solutions, or even salty broth restore sodium and potassium more effectively. Keep sipping throughout the day, and check the color of your urine as a guide. Pale or straw-colored urine means you’re adequately hydrated. Dark yellow or amber means you need to keep drinking.
Alcohol also rapidly depletes B vitamins, especially thiamine (B1). You won’t fix this in a single day, but eating nutrient-rich foods once you’re able to keep them down helps your body start recovering.
When and What to Eat
Once you’ve kept liquids down for a few hours without vomiting, your appetite will likely start returning. Begin with small portions of bland, easy-to-digest foods: plain toast, crackers, bananas, applesauce, or plain oatmeal. These foods are gentle on an inflamed stomach and help stabilize your blood sugar, which drops after heavy drinking and contributes to that shaky, weak feeling.
Avoid greasy, spicy, or acidic foods until your stomach has fully settled. Dairy can also be hard to tolerate while you’re still nauseous. Stick with bland carbohydrates for the first meal or two, then gradually return to your normal diet as you feel better.
What to Avoid
Don’t take ibuprofen or aspirin while your stomach is inflamed and you’re still vomiting. These painkillers can further irritate your stomach lining and increase the risk of bleeding. An antacid is a safer choice if you need something to settle your stomach.
Skip the “hair of the dog.” Drinking more alcohol to ease nausea just adds more of the substance that caused the problem. It delays recovery, worsens dehydration, and puts additional stress on your liver and stomach.
Avoid caffeine in large amounts. Coffee is a mild diuretic and can worsen dehydration when you’re already behind on fluids. If you normally drink coffee and skipping it would give you a withdrawal headache, a small amount is fine, but prioritize water and electrolytes first.
Signs You Need Emergency Help
Most post-drinking vomiting is miserable but not dangerous. However, alcohol overdose is a medical emergency that can be fatal, and vomiting is one of its symptoms. Call 911 immediately if you or someone you’re with shows any of these signs alongside vomiting:
- Confusion or stupor: inability to hold a conversation or understand where they are
- Difficulty staying conscious: passing out and being hard to wake up
- Slow or irregular breathing: fewer than 8 breaths per minute, or gaps of 10 seconds or more between breaths
- Seizures
- Clammy skin, bluish skin color, or extreme paleness
- No gag reflex: this means they could choke on their own vomit
Also seek medical attention if you notice blood in your vomit (it can look red or dark like coffee grounds), if vomiting continues for more than 24 hours with no improvement, or if you’re showing signs of severe dehydration: a racing heartbeat, dizziness when standing, very dark urine, or an inability to keep any fluids down at all.
Typical Recovery Timeline
For most people, the vomiting itself stops within several hours once alcohol clears the stomach. The nausea and general hangover symptoms that follow typically peak around 12 to 14 hours after your last drink and resolve within 24 hours. Some people feel rough for up to 72 hours after a particularly heavy session, but active vomiting that lasts beyond 24 hours is unusual and worth getting checked out.
During recovery, your body is processing the remaining alcohol, repairing stomach lining irritation, and restoring fluid balance. The more consistently you sip fluids and rest, the faster this process goes. There’s no shortcut that eliminates a hangover instantly, but staying hydrated and eating bland food once you’re able to are the two interventions that make the biggest practical difference in how quickly you feel normal again.
