How to Stop a Hangover Fast: What Actually Works

There’s no instant cure for a hangover, but you can cut the misery shorter by tackling the specific things your body is struggling with: dehydration, inflammation, low blood sugar, and a buildup of toxic byproducts from alcohol metabolism. The average hangover lasts about 12 hours from the time you wake up, with symptoms peaking roughly 14 hours after your last drink. What you do in the first few hours after waking determines whether you’re functional by lunch or wiped out until evening.

Why You Feel This Bad

Your liver breaks alcohol down into a toxic compound called acetaldehyde, which damages cells and triggers widespread inflammation. Your body responds by flooding your system with inflammatory molecules, the same ones responsible for the aches, fatigue, and brain fog you feel when you’re sick. That’s why a hangover can feel so similar to the flu.

On top of the inflammation, alcohol is a diuretic. You lost far more fluid overnight than you took in, and with it, electrolytes your muscles and brain need to function. Your blood sugar is also likely low because your liver was too busy processing alcohol to release stored glucose normally. Each of these problems has a different fix, and addressing all of them at once is what speeds recovery.

Rehydrate With More Than Water

Fluid volume matters more than what’s in the drink. Research comparing oral rehydration solutions (which have three times the sodium of a typical sports drink) to regular sports drinks found no meaningful difference in rehydration speed, as long as people drank enough. The takeaway: pick whatever you’ll actually drink a lot of and start immediately.

Water works. Sports drinks work. Electrolyte packets mixed into water work. Broth is especially useful because it delivers sodium, potassium, and a small amount of calories all at once. Aim to drink steadily over the first two to three hours rather than chugging a full bottle at once, which can trigger nausea. If you’re vomiting and can’t keep liquids down, take small sips every few minutes rather than giving up on fluids entirely.

Skip the Coffee

Caffeine narrows blood vessels and raises blood pressure, which can actually intensify a pounding headache rather than relieve it. Coffee is also a diuretic, meaning it pulls more water out of your body at a time when you’re already running dry. If you’re a daily coffee drinker and worried about a caffeine withdrawal headache stacking on top of the hangover, a small cup later in the morning (after you’ve rehydrated) is a reasonable compromise. But coffee first thing on an empty, dehydrated stomach will slow your recovery.

Choose the Right Pain Reliever

Ibuprofen (Advil, Motrin) is the most common choice for hangover headaches, though it can irritate a stomach that’s already inflamed from alcohol. Taking it with food reduces that risk.

Avoid acetaminophen (Tylenol) if you can. Your liver is already working overtime to clear alcohol byproducts, and acetaminophen adds to that burden. For most people, a single normal dose the day after drinking won’t cause liver damage. But if you drink regularly or heavily, the combination raises the risk of a condition called acetaminophen toxicity, which can lead to liver failure. Ibuprofen or aspirin are safer bets for a hangover, taken with food and water.

Eat Early, Even If You Don’t Want To

Your blood sugar is low and your stomach lining is irritated, so you need food that’s gentle but nutrient-dense. Eggs are one of the best options. They contain an amino acid called L-cysteine, which directly reacts with acetaldehyde (the toxic byproduct your liver is trying to clear) and helps neutralize it. Researchers at the University of Helsinki confirmed that L-cysteine alleviates hangover symptoms through this mechanism.

Beyond eggs, focus on foods that combine carbohydrates with some protein and fat: toast with peanut butter, oatmeal with banana, or rice with a fried egg. Carbohydrates help restore blood sugar, while protein and fat slow digestion and provide sustained energy. Avoid greasy, heavy meals that demand a lot from your already struggling digestive system. If eating a full plate feels impossible, start with a few crackers and work up.

Sleep More If You Can

Hangover duration correlates significantly with total sleep time, and not in the direction you’d expect. It’s not that sleeping longer causes a longer hangover. Rather, people who sleep poorly after drinking tend to have more severe, longer-lasting symptoms. Alcohol disrupts your sleep cycles, so even if you were in bed for eight hours, the quality was poor. If your schedule allows it, going back to sleep after rehydrating and eating something light is one of the most effective things you can do. Your body clears the remaining toxins faster when you’re resting.

IV Drips Are Mostly Unnecessary

Hangover IV clinics have become popular in cities, promising rapid relief through intravenous fluids, vitamins, and sometimes anti-nausea medication. The fluids do rehydrate you, but medical experts at the University of Rochester note that IV fluids aren’t recommended unless a person truly cannot keep water down. For most hangovers, oral rehydration works just as well and doesn’t carry the risks of an unnecessary IV, which can actually be dangerous for some people depending on their bloodwork and underlying health.

Electrolyte drink packets deliver a similar combination of sodium, potassium, and glucose at a fraction of the cost and without a needle. Save the IV for a situation where you’ve been vomiting for hours and genuinely can’t hydrate by mouth.

What the Recovery Timeline Looks Like

In a study tracking hangover progression hour by hour, symptoms began rising about 8 hours after drinking and peaked at 14 hours. After the 16-hour mark, severity dropped rapidly, and by 21 hours post-drinking, most people reported minimal symptoms. Interestingly, the number of drinks consumed didn’t predict how long the hangover lasted. Severity and sleep quality were the strongest predictors of duration.

If you drank until midnight, expect the worst of it between 10 a.m. and 2 p.m. the next day. With aggressive rehydration, food, rest, and a pain reliever, most people feel noticeably better by mid-afternoon. You won’t eliminate the hangover entirely, but you can compress the window of real misery from most of the day to a few hours.

The Fastest Realistic Recovery Plan

  • Immediately on waking: Drink 16 to 20 ounces of water or an electrolyte drink. Sip steadily rather than gulping.
  • Within 30 minutes: Eat something with carbs and protein. Eggs, toast, oatmeal, or a banana. Even a few bites help.
  • For headache: Take ibuprofen with food. Avoid acetaminophen.
  • For nausea: Ginger tea or ginger chews can settle your stomach. Small, frequent sips of broth also help.
  • Mid-morning: If possible, go back to sleep for an hour or two after eating and hydrating.
  • Throughout the day: Keep drinking fluids. Eat a proper meal when your stomach can handle it.

None of this is a magic bullet. Your body needs time to finish clearing acetaldehyde and calming the inflammatory response alcohol triggered. But by addressing dehydration, blood sugar, inflammation, and sleep in parallel, you give your system everything it needs to get through the process as fast as physiology allows.
