Vomiting after drinking alcohol is your body’s response to a stomach lining that’s been irritated and inflamed by excess gastric acid. The most effective things you can do at home are stop drinking immediately, sip small amounts of fluid, and rest in a safe position while your stomach settles. Most alcohol-related vomiting resolves on its own within 24 hours, but how you manage that window matters for your comfort and safety.
Why Alcohol Makes You Vomit
Alcohol triggers a spike in gastric acid production. It does this by ramping up the activity of acid-secreting receptors and proton pumps in your stomach lining, essentially flooding your stomach with digestive juice it doesn’t need. That excess acid damages the protective mucus layer of your stomach, causing acute inflammation, or gastritis. The result is nausea, pain in your upper abdomen, and vomiting.
Your body also treats alcohol as a mild poison. When blood alcohol levels rise too quickly, the brain’s vomiting center activates as a protective reflex to prevent further absorption. This is why vomiting often hits hardest after binge drinking or drinking on an empty stomach, both of which cause a rapid spike in blood alcohol.
Sip Fluids in Small Amounts
While you’re still actively vomiting, don’t try to drink a full glass of anything. Start with ice chips or small sips of water, just enough to wet your mouth. If that stays down for 15 to 20 minutes, take another sip. Gulping water when your stomach is in revolt will likely trigger another round of vomiting.
Once you’ve kept ice chips down for an hour or so, move to clear liquids: water, diluted apple juice, clear broth, or a popsicle. Keep everything flat and clear. Carbonated drinks can add gas to an already irritated stomach, making nausea worse for some people. Despite the popularity of electrolyte drinks for hangovers, there’s little evidence they work better than plain water for rehydration after drinking. Water is fine. If you happen to have an electrolyte solution on hand, it won’t hurt, but don’t feel you need to go out and buy one.
Try Ginger for Nausea
Ginger is one of the most studied natural remedies for nausea, and it genuinely works. The active compounds (gingerols) help calm the stomach and reduce the urge to vomit. Most clinical research uses a daily dose of about 1,000 mg, which translates to roughly one teaspoon of freshly grated ginger, four cups of premade ginger tea, two pieces of crystallized ginger (about one square inch each), or two teaspoons of ginger syrup.
Dried ginger powder contains the highest concentration of active compounds, followed by fresh ginger, with ginger tea products having the lowest. So if you’re choosing between options, a capsule or fresh ginger steeped in hot water will be more potent than a store-bought tea bag. That said, even weak ginger tea can take the edge off nausea when you’re in rough shape. Sip it slowly rather than drinking it all at once.
Rest in a Safe Position
If you’re lying down while nauseous or still intoxicated, position matters. Lying flat on your back creates a real risk of choking on vomit, which can block your airway or cause fluid to enter your lungs. The safest position is on your side with your head angled slightly downward. This allows vomit to drain away from your throat rather than pooling near your airway.
If you’re helping someone else who’s been vomiting and is drowsy or passed out, roll them onto their side and don’t leave them alone. Keep their head turned slightly toward the ground. This single step prevents one of the most dangerous complications of heavy drinking.
What to Eat Once Vomiting Stops
Don’t rush back to solid food. Your stomach lining is inflamed, and forcing food too early can restart the cycle. A reasonable timeline looks like this:
- First few hours: Ice chips and tiny sips of water only.
- After 6 hours with no vomiting: Clear liquids like broth, diluted juice, or flat ginger ale. Choose things with a few calories to keep your energy up.
- After 24 hours: Bland, easy-to-digest foods. The classic BRAT approach (bananas, rice, applesauce, toast) works well. Plain crackers, oatmeal, or grits are also good options. Avoid anything greasy, spicy, or acidic until your stomach feels fully settled.
What to Avoid While Recovering
Your stomach lining is already damaged, so anything that adds further irritation will make things worse. Three things to skip:
Pain relievers like ibuprofen and aspirin belong to a class of drugs that directly irritate the stomach lining. They work by suppressing the same protective mucus layer that alcohol has already compromised, increasing the risk of erosion and even ulcers. If you need pain relief for a headache, acetaminophen is gentler on the stomach, though it does put extra load on your liver, which is already processing alcohol.
Coffee and other caffeinated drinks stimulate acid production in the stomach and can worsen nausea. Hold off until you’re able to eat solid food comfortably. Acidic drinks like orange juice or tomato juice can have the same effect on raw stomach tissue.
More alcohol (“hair of the dog”) simply restarts the entire cycle of gastric irritation. It may briefly numb your symptoms, but it delays recovery and adds to the toxic load your liver is working to clear.
When Vomiting Becomes an Emergency
Most post-drinking vomiting is miserable but not dangerous. However, some situations require a 911 call. Watch for these signs, especially in someone who has been drinking heavily:
- Blood in the vomit, which can look bright red or dark like coffee grounds
- Slow breathing, fewer than eight breaths per minute
- Irregular breathing, with gaps of more than 10 seconds between breaths
- Seizures
- Skin that looks blue, gray, or unusually pale
- Inability to stay conscious or difficulty waking up
These are signs of alcohol poisoning, not just a bad hangover. Don’t wait for all of them to appear. Even one is enough to call for help. If someone is unconscious and you can’t wake them, call emergency services immediately, roll them on their side, and stay with them until help arrives.
