The most effective hangover recovery comes down to three things: rehydrating with electrolytes, eating the right foods, and giving your body time. Most hangovers last about 12 hours from the time you wake up, though the full cycle from your last drink to feeling normal averages around 18 hours. There’s no instant cure, but you can meaningfully shorten your misery and feel better faster with the right approach.
Why You Feel This Bad
Understanding what’s happening in your body helps explain why certain remedies work and others don’t. Alcohol suppresses a hormone called vasopressin, which normally tells your kidneys to hold onto water. Without it, you urinate far more than usual, losing fluids and electrolytes. That dehydration drives the thirst, fatigue, and headache you’re feeling right now.
Alcohol also increases inflammation throughout your body, the same kind of low-grade immune response that makes you feel awful when you’re sick. On top of that, your liver is busy breaking down alcohol into a toxic byproduct called acetaldehyde, which is responsible for a significant portion of hangover symptoms, including nausea, sweating, and a racing heart. Your liver eventually clears it, but there’s no way to speed that process up dramatically.
There’s also a blood sugar component. Alcohol can reduce your liver’s ability to produce new glucose by up to 45%. If you drank on an empty stomach or danced all night without eating, your blood sugar may have dropped significantly. That contributes to shakiness, weakness, brain fog, and irritability the next morning.
Rehydrate With More Than Water
Plain water helps, but it’s not the fastest path to recovery. Drinks containing sodium, potassium, and a small amount of glucose can rehydrate you up to 40% faster than water alone after alcohol consumption. The glucose isn’t just for energy; it actively helps your intestines absorb electrolytes more efficiently.
Your best options, ranked by effectiveness:
- Oral rehydration solutions like Pedialyte are formulated to match the particle concentration of your blood, which means your small intestine absorbs them quickly even when your digestion is sluggish. They contain only about 6 grams of sugar per liter, compared to 36 grams in a typical sports drink.
- Coconut water rehydrates about as well as sports drinks but with less sugar (around 6 grams per serving) and no artificial ingredients.
- Sports drinks like Gatorade work but contain more sugar than you need. They’re fine if that’s what you have on hand.
- Broth or soup provides sodium, potassium, and fluid in one package, with the added benefit of being easy on a queasy stomach.
Sip steadily rather than chugging. Your stomach is already irritated, and downing a liter of anything at once will likely make your nausea worse.
What to Eat (and When)
Eating is one of the most effective things you can do, even if your stomach protests. Your liver’s glucose-producing ability is still impaired, so you need to get blood sugar from food. Complex carbohydrates like toast, oatmeal, rice, or crackers provide a slow, steady release of glucose without overwhelming your digestive system.
Eggs are a particularly smart choice. They’re rich in an amino acid called L-cysteine, which reacts directly with acetaldehyde, the toxic alcohol byproduct your liver is trying to clear. Research from the University of Helsinki confirmed that L-cysteine helps alleviate hangover symptoms through this mechanism. You don’t need a supplement; a couple of scrambled eggs will do.
Bananas are another solid pick because they’re high in potassium, easy to digest, and provide quick natural sugar. If you can manage a more complete meal, combine protein, complex carbs, and some fat. Think eggs on toast with avocado, or oatmeal with banana and a handful of nuts. Avoid greasy, heavy foods if you’re nauseous. The classic greasy breakfast is better as a preventive measure (eaten before or during drinking) than as a cure.
Pain Relief: Choose Carefully
If your headache is unbearable, ibuprofen (Advil, Motrin) is generally the safer choice over acetaminophen (Tylenol). The combination of acetaminophen and alcohol can cause serious liver damage because both substances are processed by the same liver pathways, and your liver is already working overtime.
That said, ibuprofen and aspirin can irritate your stomach lining, which alcohol has already inflamed. Take them with food, not on an empty stomach. If your primary symptom is nausea rather than headache, skip the painkillers entirely until you’ve been able to eat something.
Rest and Sleep It Off
Sleep is genuinely restorative during a hangover, and you probably need it more than you realize. Alcohol fragments your sleep architecture throughout the night, repeatedly pulling you out of deeper sleep stages and cutting into REM sleep, the phase most important for feeling rested. Your brain cycles through brief awakenings over and over, which is why you might have slept for eight hours but feel like you got three.
If you can, go back to sleep or at least rest in a dark, quiet room. Even a 90-minute nap can help your body catch up on the restorative sleep it missed overnight. Keep water or an electrolyte drink within arm’s reach so you can sip between naps.
Coffee and Caffeine: Proceed With Caution
A cup of coffee can help with the grogginess and headache, especially if you’re a daily coffee drinker who would get a caffeine withdrawal headache on top of everything else. But caffeine is a mild diuretic, so it can work against your rehydration efforts. It can also increase stomach acid production when your stomach is already irritated.
If you want caffeine, have one cup alongside a full glass of water or electrolyte drink, and make sure you’ve eaten something first. Skip the espresso shots and energy drinks.
What Doesn’t Work
“Hair of the dog,” or 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 dehydration, inflammation, or acetaldehyde buildup. It just delays the hangover and adds more toxins for your liver to process. The symptoms will return, often worse.
Hangover supplements, IV drip bars, and activated charcoal lack strong evidence of meaningful benefit. Your body already has the machinery to clear the toxins; it just needs time, fluids, and fuel.
The Timeline for Feeling Normal
Hangover symptoms typically peak about 14 hours after you started drinking. If you stopped drinking around midnight, that means the worst hits around 2 p.m. the next day, not first thing in the morning. For most people, the full hangover lasts between 14 and 23 hours from the last drink, with an average of about 18 hours.
From the time you wake up, expect roughly 12 hours before symptoms fully resolve. The headache and nausea tend to ease first, while fatigue and brain fog can linger into the evening. Proper hydration, food, and rest can pull you toward the shorter end of that range.
Reduce Next Time’s Hangover
What you drink matters. Dark liquors like bourbon, whiskey, and red wine contain higher levels of compounds called congeners, which are byproducts of fermentation that intensify hangover symptoms. Clear spirits like vodka and gin have significantly lower congener levels. This doesn’t mean clear drinks are hangover-proof, but switching can make a noticeable difference.
The most effective preventive strategies are straightforward: alternate alcoholic drinks with water throughout the night, eat a substantial meal before drinking, and pace yourself to no more than one drink per hour. Your liver processes roughly one standard drink per hour regardless of your tolerance, so anything beyond that creates a backlog of toxins that you’ll feel the next morning.
