There’s no instant cure for a hangover, but you can speed up recovery and ease symptoms with the right combination of hydration, food, rest, and careful use of pain relievers. Most hangovers resolve within 24 hours as your liver finishes processing alcohol and its toxic byproducts. What you do in those hours makes a real difference in how miserable they feel.
Why You Feel This Bad
Your liver breaks down alcohol in two steps. First, it converts ethanol into acetaldehyde, a toxic compound. Then it converts acetaldehyde into harmless acetate. The speed of that first step matters more than you’d expect: people whose bodies clear ethanol slowly tend to have worse hangovers, because ethanol itself crosses into the brain and drives many of the symptoms you’re feeling. Meanwhile, acetaldehyde triggers inflammation and oxidative stress throughout your body, which worsens as the hours go on.
Alcohol also suppresses a hormone that helps your kidneys retain water, so you urinate far more than usual while drinking. That flushes out key electrolytes like sodium, potassium, and magnesium along with the fluid. The result is the dehydration, headache, nausea, fatigue, and brain fog you’re dealing with right now.
Rehydrate With More Than Water
Water is essential, but it’s only part of the fix. When you’ve lost significant fluid and electrolytes, plain water alone won’t restore full balance. An electrolyte drink, coconut water, or even broth will replenish the sodium, potassium, and magnesium your body dumped overnight. Sip steadily rather than chugging. If you’re nauseous, small frequent sips are easier to keep down than large glasses.
A reasonable target is to drink at least 16 to 24 ounces of fluid in the first hour after waking, then continue drinking throughout the day. Shifts in potassium and magnesium levels can affect how your heart and muscles function, so replacing those minerals genuinely matters for how quickly you bounce back.
What to Eat
Eggs are one of the best hangover foods for a specific reason: they’re rich in the amino acid cysteine, which your body uses to produce glutathione, a powerful antioxidant. Drinking alcohol depletes your glutathione stores, and without enough of it, your body struggles to break down acetaldehyde. Eating eggs helps replenish that supply.
Fruit and honey are also worth reaching for. Fructose, the natural sugar in fruit and honey, has been shown to increase the rate of alcohol metabolism by more than 50% in liver cell studies. Your body uses fructose to help regenerate the chemical resources your liver needs to keep processing alcohol’s byproducts. Bananas are a particularly good choice because they combine fructose with potassium. Toast or crackers can help settle your stomach if nausea is a problem, giving your digestive system something bland to work with.
Pain Relievers: Choose Carefully
If your headache is unbearable, ibuprofen is generally the safer option compared to acetaminophen (Tylenol), but it comes with a caveat. Both aspirin and ibuprofen can irritate an already-inflamed stomach lining, so take them with food and water rather than on an empty stomach.
Acetaminophen is the riskier choice after drinking. Your liver processes both alcohol and acetaminophen, and heavy drinking depletes the same glutathione stores your liver needs to safely handle acetaminophen. That combination can lead to acetaminophen toxicity, which accounts for nearly half of acute liver failure cases in North America. If you drink regularly or heavily, keep acetaminophen doses under 2,000 mg per day and avoid using it as your go-to hangover remedy.
Skip the Coffee (or Keep It Small)
Coffee feels like the obvious move, but it can backfire. Caffeine is a diuretic, meaning it increases urine output and can slow down the rehydration process your body desperately needs. It also narrows blood vessels and raises blood pressure, which can make a pounding headache worse rather than better.
The exception: if you drink coffee every morning, skipping it entirely could trigger a caffeine withdrawal headache on top of your hangover. In that case, have a small cup alongside plenty of water or an electrolyte drink. Just don’t rely on coffee as the fix.
Why “Hair of the Dog” Doesn’t Work
Drinking more alcohol the next morning can temporarily mask hangover symptoms by raising your blood alcohol level and triggering a short-lived endorphin boost. But hangover symptoms are worst when blood alcohol drops back to zero. All you’re doing is delaying that moment. When you eventually stop drinking, the hangover returns, often worse because your body now has even more alcohol to process. This approach also edges toward a pattern of dependence, where you need alcohol to feel normal after drinking.
Supplements That Show Promise
Red ginseng has some of the stronger evidence behind it. In a randomized crossover study of 25 healthy men, those who drank a red ginseng beverage alongside whiskey had significantly lower blood alcohol concentrations at 30, 45, and 60 minutes compared to those who drank a placebo. They also reported less severe hangover symptoms. Red ginseng appears to help the body clear alcohol faster.
Dihydromyricetin (DHM), a compound extracted from the Japanese raisin tree, has shown protective effects against alcohol-related liver inflammation and fat accumulation in animal studies. It reduced several markers of inflammation and appeared to support liver health during alcohol exposure. Human clinical trials are limited, so the evidence is still preliminary, but DHM supplements are widely available and generally well-tolerated.
What Actually Helps Most
Sleep is the most underrated hangover remedy. Alcohol disrupts sleep architecture, so even if you were in bed for eight hours, you likely didn’t get quality rest. Your body does most of its repair work during sleep, so if you can nap, do it. A dark, cool room with a glass of water and electrolytes on the nightstand will do more for you than most things you can buy at a pharmacy.
The practical recovery plan is straightforward: drink electrolytes, eat eggs or fruit, take ibuprofen with food if needed, rest, and give your liver time. Most hangovers peak in the morning and improve steadily through the afternoon. By the 24-hour mark, your body has typically cleared the backlog and you’ll feel close to normal.
