The fastest way to get over a hangover is to rehydrate, eat something, rest, and wait it out. There’s no instant cure, but the right combination of fluids, food, and pain relief can meaningfully shorten your misery. Most hangovers resolve within 8 to 24 hours, with symptoms peaking around the time your blood alcohol level drops to zero, typically six to eight hours after your last drink.
Why You Feel This Bad
A hangover isn’t just dehydration, though that’s part of it. When your body breaks down alcohol, the process triggers an inflammatory response similar to fighting an infection. Your blood levels of specific immune signaling molecules rise, and the higher those levels climb, the worse your hangover feels the next day. This inflammation drives the headache, nausea, fatigue, and general achiness that make you want to stay in bed.
Alcohol also disrupts your blood sugar. Your liver is so busy processing alcohol that it can’t release stored glucose normally. If you drank on an empty stomach or didn’t eat enough beforehand, your blood sugar drops, adding shakiness, weakness, and brain fog on top of everything else. Meanwhile, alcohol acts as a diuretic, flushing fluids and electrolytes faster than you’d normally lose them.
Rehydrate, But Do It Right
Water alone helps, but it’s not the whole picture. You’ve lost electrolytes (sodium, potassium, magnesium) along with all that fluid, so drinks that replace those minerals will get you feeling better faster. Sports drinks, coconut water, or oral rehydration solutions all work well. Pedialyte has become a popular choice because it has a higher electrolyte concentration than most sports drinks.
Sip steadily rather than chugging. If you’re nauseous, drinking too much too fast can make your stomach rebel. Small, frequent sips over a couple of hours are easier to keep down and absorb just as effectively.
Skip the Coffee
A cup of coffee sounds like the obvious move when you’re exhausted, but it can backfire. Coffee is also a diuretic, which means it pulls more water out of your system and slows down rehydration. Caffeine narrows blood vessels and raises blood pressure, which can actually intensify a hangover headache rather than relieve it. If you’re a daily coffee drinker and skipping it would give you a withdrawal headache on top of everything, a small cup is reasonable. But don’t count on it as a recovery tool.
Eat Something, Even If You Don’t Want To
Your blood sugar is likely low, and eating is the most direct fix. Bland, carbohydrate-rich foods are your best bet: toast, crackers, bananas, oatmeal, or rice. These are gentle on an irritated stomach and help stabilize glucose levels. Bananas pull double duty by replenishing potassium you’ve lost.
Eggs are another solid choice. They contain an amino acid called cysteine, which helps your body process some of alcohol’s toxic byproducts. A simple breakfast of eggs and toast covers your bases: protein, carbs, and something easy to digest. Avoid greasy or heavily spiced food if your stomach is already upset. The “greasy breakfast cure” is more likely to trigger nausea than fix anything.
Choosing the Right Pain Reliever
This is where people often make a mistake. Acetaminophen (Tylenol) is hard on your liver, and your liver is already working overtime to clear alcohol from your system. Overdosing on acetaminophen is the most common cause of acute liver failure, and combining it with recent heavy drinking raises that risk. Avoid it on hangover mornings.
Ibuprofen (Advil, Motrin) or naproxen (Aleve) are generally the safer pick for hangover headaches because they reduce inflammation, which is a core driver of your symptoms. That said, these medications can irritate the stomach lining, especially on an empty stomach or after heavy drinking. Take them with food and water, and stick to the lowest effective dose. If your stomach is already in rough shape, it may be better to hold off entirely.
Rest and Sleep It Off
Alcohol disrupts your sleep architecture even if you were unconscious for eight hours. You likely got less deep, restorative sleep than your body needed. A nap or even just lying down in a dark, quiet room lets your body redirect energy toward recovery. There’s no way to rush the metabolic process of clearing alcohol’s byproducts from your system, so giving your body downtime is one of the most effective things you can do.
What About Supplements?
Dihydromyricetin (DHM), a compound found in the Japanese raisin tree, has gained popularity as a hangover supplement. It appears to help the body break down alcohol byproducts and may protect the liver from alcohol-related damage. Clinical trials have shown it can reduce certain hangover symptoms, though it works best when taken before or during drinking rather than the morning after. If you’re already in the thick of a hangover, DHM is unlikely to be a dramatic rescue.
B vitamins and zinc have some evidence behind them as well. Alcohol depletes both, and people with higher dietary intake of these nutrients tend to report less severe hangovers. A basic multivitamin or B-complex with water won’t hurt and may help at the margins.
Why Some Drinks Cause Worse Hangovers
Not all alcohol is created equal when it comes to the morning after. Darker liquors like bourbon, whiskey, and brandy contain higher levels of congeners, which are chemical byproducts of fermentation that your body has to process on top of the alcohol itself. Research has confirmed that bourbon produces noticeably worse hangovers than vodka, which has very few congeners. Beer generally falls somewhere in between. Red wine is another common offender due to its congener content and histamines.
This doesn’t help you now, but it’s worth remembering next time. If you’re prone to bad hangovers, sticking to clear spirits like vodka or gin (mixed with non-sugary drinks) tends to produce milder aftereffects.
The Recovery Timeline
Hangover symptoms typically begin six to eight hours after heavy drinking, as your blood alcohol level drops toward zero. For most people, the worst of it hits in the morning and gradually eases over the next 8 to 24 hours. Lighter hangovers may clear by early afternoon. Heavier ones, especially after a full night of drinking, can linger into the evening.
If your symptoms last beyond 24 hours, or if you experience confusion, seizures, repeated vomiting, or extremely slow breathing, that’s not a normal hangover. Those are signs of alcohol poisoning or withdrawal, which require medical attention. A standard hangover, however miserable, resolves on its own with time, fluids, food, and rest.
