There’s no instant cure for a hangover, but you can speed up recovery and ease the worst symptoms with a combination of rehydration, food, rest, and the right pain reliever. Most hangovers resolve within 24 hours, and the strategies below can shorten that window noticeably.
Why You Feel This Bad
A hangover is the result of several things happening at once. Alcohol is a diuretic, so you’ve lost more fluid and electrolytes than usual. Your liver has been busy processing alcohol as a priority, which means it paused other jobs, including releasing stored glucose into your bloodstream. That drop in blood sugar is a major reason you feel shaky, foggy, and exhausted the morning after.
On top of that, alcohol triggers an inflammatory response throughout your body and irritates the lining of your stomach. The combination of dehydration, low blood sugar, inflammation, and poor sleep quality creates the classic package: headache, nausea, fatigue, and difficulty concentrating.
Rehydrate With Electrolytes, Not Just Water
Water alone helps, but it doesn’t replace the sodium, potassium, and magnesium you lost overnight. Drinking a sports drink, coconut water, or even broth will restore those electrolytes faster. If you don’t have any of those on hand, adding a pinch of salt to a glass of water with a squeeze of lemon does the job reasonably well.
Aim to drink at least 16 to 24 ounces of fluid in the first hour after waking up, then keep sipping steadily. If you’re nauseous and can’t drink much at once, take small sips every few minutes rather than forcing a full glass down.
Eat Something, Even If You Don’t Want To
Your blood sugar is likely low because your liver spent the night processing alcohol instead of releasing stored glucose into your bloodstream. Eating carbohydrate-rich food is the fastest way to correct that. Toast, crackers, oatmeal, bananas, or rice are all easy on a queasy stomach and will bring your blood sugar back up. Eggs are a popular hangover food for good reason: they contain an amino acid called cysteine that helps your body clear acetaldehyde, the toxic byproduct of alcohol metabolism.
A combination of complex carbohydrates and some protein (think toast with eggs, or oatmeal with a banana) gives you both a quick glucose boost and sustained energy over the next few hours. Avoid greasy, heavy meals if your stomach is already upset. Despite the cultural reputation of a “greasy breakfast,” fat slows digestion and can make nausea worse.
Choose the Right Pain Reliever
Headache is usually the symptom people want to tackle first, and your choice of painkiller matters more than you might think.
Acetaminophen (Tylenol) is risky after heavy drinking. Your liver is already working hard to clear alcohol, and acetaminophen adds to that burden. Overdose of acetaminophen is the most common cause of acute liver failure, and combining it with alcohol significantly raises the risk of liver damage.
Ibuprofen (Advil, Motrin) or naproxen (Aleve) are generally the better option for a hangover headache. However, these anti-inflammatory drugs can irritate your stomach lining, which alcohol has already inflamed. Take them with food and water, not on an empty stomach. If you drink heavily on a regular basis, be aware that frequent use of these medications alongside alcohol can also stress the liver over time.
Sleep and Rest
Alcohol disrupts your sleep architecture, particularly the deeper, more restorative stages. Even if you slept for eight hours, you likely didn’t get quality rest. If your schedule allows it, going back to sleep for a couple of hours after hydrating and eating something is one of the most effective things you can do. Your body clears the remaining toxins faster while you’re resting, and the fatigue and brain fog improve dramatically with even a short nap.
Your Drink Choice Affects Recovery Time
Not all alcohol creates equal hangovers. Darker drinks contain higher levels of congeners, which are chemical byproducts of fermentation that make hangovers worse. Red wine, brandy, and whiskey have the highest congener concentrations. Beer and vodka have the lowest. Research has consistently shown that with the same amount of alcohol consumed, spirits produce worse hangovers than wine or beer.
This won’t help you right now, but it’s worth knowing for next time: choosing lighter-colored drinks and sticking to one type of alcohol generally leads to a milder morning after.
What Doesn’t Work
“Hair of the dog,” or drinking more alcohol, delays the hangover rather than curing it. You’re simply postponing the inevitable while adding more toxins for your liver to process. Coffee can help with the headache if you’re a regular caffeine drinker (since caffeine withdrawal compounds the headache), but it’s also a diuretic that can worsen dehydration. If you drink coffee, match it with an equal amount of water.
Activated charcoal supplements are marketed for hangovers but have no evidence supporting their use. By the time you’re hungover, the alcohol has long since left your stomach and been absorbed into your bloodstream. Charcoal can’t pull it back out.
A Practical Recovery Timeline
For a moderate hangover (four to six drinks the night before for most adults), expect the worst symptoms to peak about 12 to 14 hours after your last drink. If you stopped drinking at midnight, you’ll likely feel worst between 10 a.m. and 2 p.m. With active rehydration and food, most people feel significantly better by late afternoon.
A severe hangover from heavier drinking can linger into the following day. The nausea typically fades first, followed by the headache, with fatigue and brain fog being the last to clear. If you’re still vomiting more than 24 hours later, can’t keep fluids down, or notice confusion or a rapid heartbeat, that crosses from hangover into something that needs medical attention.
Prevention Tactics That Actually Help
Alternating every alcoholic drink with a glass of water is the single most effective prevention strategy. It slows your drinking pace, keeps you hydrated, and reduces your total alcohol intake without much effort. Eating a substantial meal before drinking also slows alcohol absorption significantly.
Setting a firm drink limit before you start, choosing lower-congener drinks like vodka or white wine, and stopping at least two to three hours before bed (giving your body time to start processing alcohol before sleep) all reduce hangover severity the next morning.
