There is no true cure for a hangover, but you can significantly shorten how miserable you feel. Most hangovers last about 12 hours after you wake up, with symptoms peaking roughly 14 hours after your last drink. The goal is to support what your body is already doing: clearing inflammatory byproducts, restoring fluids, and stabilizing blood sugar.
Why You Feel This Bad
Alcohol triggers an immune response similar to fighting off an infection. Drinking raises levels of inflammatory molecules in your blood, and the higher those levels climb, the worse your hangover feels the next day. At the same time, alcohol acts as a diuretic, pulling water and electrolytes out of your system. If you vomited, that loss is even greater.
Your liver is also working overtime. It converts alcohol into a toxic intermediate compound, then breaks that down further into harmless acetate. That middle step generates oxidative stress, essentially free radical damage that contributes to the headache, nausea, and general fog. Your body can handle this process on its own, but it takes time, and the strategies below help reduce the collateral damage while it works.
Rehydrate With More Than Water
A glass of water first thing in the morning is the simplest move you can make. But if your hangover involved vomiting or heavy sweating, plain water won’t replace the sodium, potassium, and other electrolytes you lost. Sports drinks or oral rehydration solutions like Pedialyte are better choices in that case. Sip steadily rather than chugging. Flooding your stomach with a large volume of liquid at once can trigger more nausea.
Eat the Right Foods Early
Alcohol interferes with your liver’s ability to release stored sugar into your bloodstream, which is part of why you feel shaky, weak, and foggy the morning after. Eating carbohydrate-rich foods helps correct that drop in blood sugar. The classic BRAT foods (bananas, rice, applesauce, toast) are gentle on a queasy stomach while delivering the carbs your body needs.
Eggs are a particularly good hangover food. They’re rich in an amino acid called L-cysteine, which your body uses to produce glutathione, a key molecule involved in neutralizing alcohol’s toxic byproducts. You don’t need to think of eggs as medicine, but there’s a real biochemical reason they’ve been a hangover breakfast staple for generations. Pair them with toast or a banana and you’re covering both blood sugar and detoxification support in one meal.
Choose Your Pain Reliever Carefully
An over-the-counter anti-inflammatory like ibuprofen can help with a pounding headache, but it comes with a tradeoff: both ibuprofen and aspirin irritate the stomach lining, which alcohol has already inflamed. If your hangover is mostly headache without much nausea, a standard dose of ibuprofen is reasonable. Take it with food to reduce stomach irritation.
Avoid acetaminophen (Tylenol) when you’re hungover. Your liver is already busy processing alcohol, and acetaminophen puts additional strain on the same detoxification pathway. Alcohol depletes the glutathione stores your liver needs to safely handle acetaminophen. This combination is a leading contributor to acute liver failure in North America. Even if you’re a light drinker, it’s worth picking a different pain reliever on hangover mornings.
Sleep Is the Fastest Accelerator
Alcohol fragments your sleep architecture, reducing the restorative deep sleep stages even if you were “passed out” for hours. Much of the fatigue and brain fog of a hangover comes from poor sleep quality rather than just the alcohol itself. If your schedule allows it, going back to sleep after hydrating and eating something is one of the most effective things you can do. Your body clears inflammatory byproducts more efficiently during sleep, and you skip past the worst symptom window, which peaks around 14 hours after your last drink.
What Doesn’t Work
“Hair of the dog,” drinking more alcohol the next morning, is one of the most persistent hangover myths. It does temporarily mask symptoms by putting alcohol back into your system, but it doesn’t resolve the underlying inflammation or dehydration. It simply delays the hangover and adds more toxic load for your liver to process. The symptoms will return, often worse.
Coffee is a mixed bag. Caffeine can ease a headache through vasoconstriction and help with alertness, but it’s also a diuretic that can worsen dehydration. If you’re a regular coffee drinker, a small cup with plenty of water alongside it is fine. It won’t speed your recovery, but it may prevent a caffeine withdrawal headache from stacking on top of your hangover.
A Realistic Recovery Timeline
From the moment you stop drinking, the average hangover lasts about 18 hours total, though the range spans roughly 14 to 23 hours depending on how much you drank and individual factors like body weight and genetics. For most people, that means waking up feeling rough and gradually improving over the course of 12 hours. Symptoms tend to be worst in the morning and ease noticeably by mid-afternoon.
There’s no shortcut that compresses this timeline to an hour or two. But combining rehydration, food, an appropriate pain reliever, and rest can take the edge off the worst hours considerably. By late afternoon, most people feel functional again. The real fast-track strategy, less satisfying but honest, is drinking less or alternating alcoholic drinks with water the night before. Hangover severity tracks directly with how high your blood alcohol concentration climbed, so anything that slows the rise makes the next day meaningfully easier.
