The fastest way to get over a hangover is to rehydrate with electrolytes, eat something substantial, and manage your headache with the right pain reliever. Most hangovers resolve within 24 hours, peaking right around the time alcohol fully leaves your bloodstream. There’s no instant cure, but the right steps can shorten your misery and help your body recover faster.
Why You Feel This Bad
When you drink, your liver converts alcohol into a toxic compound called acetaldehyde. Normally, a second enzyme breaks that down quickly into something harmless. But when you drink more than your liver can keep up with, acetaldehyde builds up. It’s the primary driver behind nausea, headache, facial flushing, and that general feeling of being poisoned, because you literally are.
On top of that, alcohol is a diuretic. It tells your kidneys to release more urine than usual, which drains your body of water and essential minerals like sodium and potassium. That’s why you wake up with a dry mouth, dizziness, and fatigue. Your blood sugar also drops after heavy drinking, which adds to the shakiness, brain fog, and weakness. Meanwhile, your immune system has kicked off an inflammatory response, producing compounds that contribute to headache, muscle aches, and irritability.
Rehydrate With More Than Water
Water helps, but it’s not the most efficient option. Plain water contains no electrolytes, and without enough sodium, your kidneys flush out much of what you just drank. An oral rehydration solution like Pedialyte contains two to three times more electrolytes and about 25 to 50% less sugar than typical sports drinks. That precise ratio of sugar and salt pulls fluid into your bloodstream faster than water alone.
Sports drinks are a step up from water but contain more sugar, which can slow absorption. If all you have is water, drink it steadily rather than chugging it. Adding a pinch of salt and a splash of juice gets you closer to a rehydration solution. Aim to drink at least a few glasses in the first hour or two after waking, then keep sipping throughout the day.
Eat the Right Foods
Your blood sugar is likely low, and your liver is working overtime. Eating is one of the most effective things you can do, even if your stomach protests at first. Protein helps stabilize blood sugar levels, which tend to dip after drinking. Eggs, oatmeal, and lean meats are especially good choices because they’re rich in an amino acid called L-cysteine, which supports your liver in processing alcohol’s toxic byproducts. A single cup of oatmeal provides around 227 mg of L-cysteine, while a serving of tuna or steak delivers over 500 mg.
Complex carbohydrates like toast, bananas, or rice bring your blood sugar back up gradually without the crash you’d get from sugary foods. A banana also replaces some of the potassium you lost overnight. If nausea makes eating difficult, start small. A few crackers or a piece of toast can settle your stomach enough to eat a proper meal an hour later.
Choose the Right Pain Reliever
Reaching for acetaminophen (Tylenol) when you’re hungover is risky. Alcohol depletes a protective substance in your liver, and adding acetaminophen on top of that makes your liver more susceptible to damage. Acetaminophen toxicity accounts for nearly half of acute liver failure cases in North America. This isn’t just a concern for heavy drinkers. Even moderate drinking combined with standard doses can stress the liver.
NSAIDs like ibuprofen (Advil) or aspirin are safer choices for hangover headaches. They also reduce inflammation, which is part of what’s causing your symptoms. The tradeoff is that they’re harder on your stomach, which may already be irritated from alcohol. Taking them with food helps.
Skip the “Hair of the Dog”
Drinking more alcohol the next morning can temporarily mask hangover symptoms, but only by delaying the inevitable. One theory is that it works by blocking the breakdown of methanol, a trace compound in many drinks, temporarily postponing the toxic buildup. The problem is that once the new alcohol wears off, your body still has to process everything, and now there’s more of it.
Beyond delaying recovery, this habit carries real risk. Surveys of college students found that 25 to 56% have tried drinking to relieve a hangover, and the behavior is consistently linked to heavier drinking patterns and higher rates of alcohol use disorders over time.
Rest and Wait It Out
Hangover symptoms peak when alcohol has fully cleared your system and can last up to 24 hours or longer. Sleep is one of the most underrated remedies. Alcohol disrupts your sleep architecture, meaning the sleep you got while drunk was shallow and fragmented. A long nap or an early bedtime the next night helps your body catch up on the restorative sleep it missed.
Light movement, like a short walk, can boost circulation and mood without taxing your already-depleted body. Intense exercise is counterproductive. You’re dehydrated, your coordination is off, and your heart is already working harder than usual.
What You Drink Matters for Next Time
Not all drinks produce the same hangover. Darker alcohols like bourbon, whiskey, and red wine contain higher levels of congeners, which are chemical byproducts of fermentation. Research comparing bourbon to vodka found that bourbon, a high-congener liquor, produced significantly more severe hangovers than vodka, which contains very few congeners. Beer also tends to have more congeners than clear spirits.
If you’re prone to rough mornings, sticking to lighter-colored drinks like vodka, gin, or white wine can make a noticeable difference. Alternating alcoholic drinks with water during the night slows your intake and keeps dehydration from compounding. Eating before and during drinking also slows alcohol absorption, giving your liver more time to keep up.
One small study found that prickly pear extract, taken five hours before drinking, cut the risk of a severe hangover roughly in half. Participants who took it had less nausea, dry mouth, and loss of appetite, along with lower levels of an inflammatory marker produced by the liver. It’s not widely available as a standard supplement, but it’s one of the few remedies with clinical data behind it for prevention.
