The fastest way to ease nausea from drinking is to sip small amounts of water, eat something bland and starchy, and let your stomach settle in an upright or slightly reclined position. Most alcohol-related nausea peaks six to eight hours after your last drink and clears within 24 hours. While there’s no instant cure, several strategies can shorten that window and make it more bearable.
Why Alcohol Makes You Nauseous
Your body breaks alcohol down into a toxic byproduct called acetaldehyde. In most people, a second enzyme quickly converts acetaldehyde into something harmless, but when you drink heavily, that system gets overwhelmed. Acetaldehyde builds up in your blood and triggers nausea, headache, and flushing. Some people (particularly those of East Asian descent) carry a genetic variant that makes this conversion much slower, which is why even small amounts of alcohol can make them feel sick.
Alcohol also irritates your stomach lining directly. It increases acid production and inflames the tissue, which is why nausea from drinking often comes with heartburn, bloating, and a general sense of fullness. On top of that, alcohol lowers your blood sugar and causes dehydration, both of which feed into that queasy, weak feeling.
Rehydrate, but Slowly
Alcohol is a diuretic, so by the time you feel nauseous, you’re likely dehydrated. But gulping a full glass of water on a churning stomach can make things worse. Take small sips every few minutes instead. Water is fine. If you can tolerate it, a drink with electrolytes (a sports drink, coconut water, or an oral rehydration solution) helps replace the sodium and potassium you’ve lost. Avoid anything carbonated if the fizz makes your stomach feel more unsettled, though some people find flat ginger ale or soda water helpful.
Eat Something Simple
An empty stomach amplifies nausea. Alcohol suppresses your body’s ability to maintain normal blood sugar, and that dip contributes to the shaky, nauseous feeling. The Mayo Clinic recommends 15 to 20 grams of fast-acting carbohydrates to correct low blood sugar: fruit juice, honey, crackers, or a piece of toast. Start small. A few bites of plain bread, rice, or a banana gives your stomach something neutral to work with and helps stabilize glucose levels. Rich, greasy, or heavily spiced food is likely to make things worse.
Ginger and Other Natural Options
Ginger has well-documented anti-nausea properties, primarily studied in pregnancy and chemotherapy but widely used for general stomach upset. Ginger tea, ginger chews, or even a small piece of raw ginger can help calm your stomach. Peppermint tea is another option: the menthol relaxes the muscles lining your digestive tract, which can ease that clenched, about-to-vomit sensation. Neither is a miracle fix, but both are gentle enough that they won’t add to your stomach’s irritation.
Fresh air and cool temperatures also help. If you’re lying in a warm room, cracking a window or sitting outside for a few minutes can reduce the intensity of nausea. Lying completely flat sometimes worsens it, so prop yourself up at a slight angle.
Over-the-Counter Medications That Help
Bismuth subsalicylate (the active ingredient in Pepto-Bismol) is one of the better-studied options. In a randomized, double-blind trial where participants overindulged at a simulated cocktail party, those who took bismuth subsalicylate had significantly better relief of nausea, heartburn, stomach pain, and bloating compared to placebo. Relief also came faster. Participants took doses every 30 to 60 minutes as needed, up to eight doses in 24 hours, with no adverse reactions reported.
Antacids containing calcium carbonate (like Tums) can help if heartburn is part of the picture, since they neutralize the excess stomach acid that alcohol triggers. Dimenhydrinate (Dramamine) or meclizine, typically used for motion sickness, can reduce nausea as well, though they’ll make you drowsy.
Skip the Ibuprofen
It’s tempting to reach for ibuprofen or aspirin to deal with the headache that comes alongside nausea, but NSAIDs combined with alcohol irritate the stomach lining and raise the risk of bleeding or ulcers. That risk climbs if you’re over 60, have a history of stomach problems, or regularly drink three or more alcoholic beverages a day. Acetaminophen (Tylenol) is also risky after heavy drinking because your liver is already working overtime to process the alcohol. If pain is severe, a small dose of acetaminophen is generally considered less harmful to the stomach than NSAIDs, but moderation matters.
What You Drank Matters
Not all alcohol produces the same hangover. Darker spirits like bourbon, brandy, and red wine contain higher levels of congeners, which are chemical byproducts of fermentation and distilling. Research comparing bourbon (high congeners) to vodka (virtually no congeners) found that bourbon produced notably worse hangover symptoms. Ethanol itself is still the primary driver of how bad you feel, so volume matters most. But if you’re especially prone to nausea, lighter-colored drinks tend to be easier on your system the morning after.
How Long It Lasts
Hangover nausea typically begins once your blood alcohol level drops significantly, usually six to eight hours after your last drink. For most people, symptoms ease within eight to 24 hours. If you’re still vomiting after 24 hours, can’t keep any fluids down, or notice signs of severe dehydration (dark urine, dizziness when standing, rapid heartbeat), that warrants medical attention.
There’s a meaningful difference between a rough hangover and alcohol poisoning. Warning signs of poisoning include confusion, seizures, slow or irregular breathing (fewer than eight breaths per minute, or gaps longer than 10 seconds between breaths), blue or gray skin, low body temperature, and inability to stay conscious. You don’t need to see all of these signs to act. A person who has passed out and can’t be woken could die. Call emergency services immediately.
Prevention for Next Time
The most effective prevention is simply drinking less, but a few practical habits reduce nausea risk when you do drink. Eating a substantial meal before drinking slows alcohol absorption and protects your stomach lining. Alternating each alcoholic drink with a glass of water cuts your total intake and keeps you hydrated. Sticking to lower-congener drinks (vodka, gin, light beer, white wine) over bourbon, scotch, or dark rum reduces the chemical load your body has to process. And pacing yourself to roughly one drink per hour gives your liver time to keep up, preventing the acetaldehyde buildup that makes you feel terrible in the first place.
