How to Cure a Bad Hangover: What Actually Works

There’s no instant cure for a hangover, but you can significantly reduce how miserable you feel and speed your recovery with the right combination of hydration, food, pain relief, and rest. Most hangover symptoms peak once your body has fully processed the alcohol, meaning you often feel worst the morning after, and symptoms can drag on for 24 hours or longer.

What’s actually happening inside your body: as your liver breaks down alcohol, it produces a toxic byproduct called acetaldehyde. This compound lingers in your system before being converted into harmless acetic acid, and while it’s circulating, it’s responsible for much of the nausea, headache, and overall awful feeling. Your job is to support your body while it finishes that cleanup process.

Rehydrate Strategically

Alcohol is a diuretic, meaning it pulls water out of your body faster than normal. By the time you wake up with a hangover, you’re likely significantly dehydrated, which contributes to headache, dizziness, and fatigue. Water is your first priority. Drink a full glass right away and keep sipping steadily throughout the day rather than chugging large amounts at once.

Adding electrolytes helps more than water alone. Sports drinks, coconut water, or even a pinch of salt in water with a squeeze of lemon will replace the sodium and potassium you lost overnight. Broth or bouillon is another solid option because it delivers both fluid and salt in an easy-to-stomach form, which matters if your nausea is strong.

Eat Something, Even If You Don’t Want To

Drinking lowers your blood sugar, and many people skip meals while drinking, compounding the drop. Some of the fatigue and brain fog you’re feeling is literally your brain running low on fuel. Toast and juice is the classic gentle approach for good reason: simple carbohydrates nudge your blood sugar back toward normal without demanding much from your already irritated stomach.

Eggs are a particularly good hangover food. They contain an amino acid called cysteine, which your body uses in processes that help neutralize acetaldehyde. Bananas replace lost potassium. Oatmeal provides slow-releasing energy. The key is eating something bland and easy to digest. Greasy food won’t “absorb” alcohol that’s already in your bloodstream, but if it sounds appealing and you can keep it down, the calories and salt still help.

Choose the Right Pain Reliever

For a pounding headache, ibuprofen (Advil), aspirin, or naproxen (Aleve) are your best options. These reduce the inflammation that contributes to hangover headaches. If your stomach is already very sensitive, ibuprofen can irritate it further, so take it with food.

The one pain reliever to avoid is acetaminophen (Tylenol). Both acetaminophen and alcohol are processed by your liver using the same protective molecule called glutathione. Drinking depletes your liver’s glutathione stores, and adding acetaminophen on top of that can push your liver toward toxicity. According to Cleveland Clinic, people who drink heavily should keep acetaminophen doses under 2,000 mg per day, but when you’re hungover, it’s simplest to just reach for ibuprofen instead. Acetaminophen toxicity accounts for nearly half of acute liver failure cases in North America, and combining it with alcohol is one of the most common ways people get into trouble.

Why Some Drinks Cause Worse Hangovers

Not all alcohol punishes you equally. Darker liquors like bourbon, brandy, and red wine contain higher levels of congeners, the chemical compounds that give drinks their color and flavor. Research published in Alcohol and Alcoholism confirms that drinks with more congeners produce more severe hangovers, and it takes fewer of those drinks to trigger one.

Vodka, gin, and white rum sit at the low end of the congener scale. This doesn’t make them hangover-proof, since alcohol itself is the primary culprit, but if you consistently feel worse after whiskey than after vodka at the same quantity, congeners are the likely explanation. For next time, lighter-colored drinks are a marginally safer bet.

What About Supplements and Remedies?

Most hangover “cures” sold in stores have little evidence behind them, but one supplement has shown modest results in clinical testing. Prickly pear extract, taken before drinking, cut the risk of a severe hangover roughly in half in a study published in JAMA Internal Medicine. The catch: it needs to be taken hours before you drink, so it’s a prevention tool, not a morning-after fix.

B vitamins and zinc have shown some correlation with less severe hangovers in survey data, though the evidence isn’t strong enough to call them reliable treatments. A multivitamin won’t hurt and may help replace nutrients lost during a night of heavy drinking. Coffee can help with the fatigue and headache if you’re a regular caffeine drinker, but it’s also a mild diuretic, so pair it with extra water.

Sleep and Time Are Doing the Real Work

Alcohol disrupts sleep quality even when it seems to knock you out. You likely got less restorative deep sleep than usual, which is a major reason you feel so drained. If you can, go back to sleep or rest after hydrating and eating something. Your liver processes alcohol at a fixed rate, roughly one standard drink per hour, and no supplement or food will meaningfully speed that up. Sleep lets the clock run while sparing you the experience of waiting it out.

Hangover symptoms peak once your blood alcohol level drops back to zero, which is why you can feel fine at 2 a.m. and terrible at 8 a.m. From that peak, most people start feeling noticeably better within 12 hours, though a truly heavy night can leave lingering fatigue and brain fog for a full 24 hours. Gentle movement like a short walk can improve circulation and mood, but intense exercise while dehydrated and depleted will likely make you feel worse.

Prevention Beats Every Cure

The only guaranteed way to avoid a hangover is drinking less, but some practical strategies reduce severity when you do drink. Eating a substantial meal before drinking slows alcohol absorption significantly. Alternating each alcoholic drink with a glass of water cuts your total intake and keeps you hydrated simultaneously. Sticking to lighter-colored, lower-congener drinks helps at the margins.

Drinking a large glass of water and eating a small snack before bed catches some of the dehydration and blood sugar drop before they compound overnight. None of this is glamorous advice, but it’s the difference between a mild headache and a day lost on the couch. Your body has exactly one way to clear alcohol: time and liver function. Everything else you do is just making the wait more comfortable.
