The most important things to do after binge drinking are to hydrate with electrolytes, eat something to stabilize your blood sugar, and rest. Your body processes roughly one standard drink per hour, so if you had eight drinks, you’re looking at about eight hours before alcohol fully clears your system. There’s no way to speed that up, but you can support your body while it does the work.
Know the Emergency Signs First
Before anything else, make sure what you’re dealing with is a bad hangover and not alcohol poisoning. The National Institute on Alcohol Abuse and Alcoholism identifies these as signs of an alcohol overdose: mental confusion or stupor, inability to wake up, vomiting while unconscious, seizures, breathing slower than 8 breaths per minute, gaps of 10 seconds or more between breaths, clammy skin, bluish skin color, and extremely low body temperature. If you or someone near you has any of these symptoms, call 911. A person who has passed out can still die from alcohol already in their stomach continuing to enter the bloodstream.
Hydrate With More Than Just Water
Heavy drinking depletes your body’s key minerals, not just water. Sodium, potassium, and magnesium levels all drop during and after a binge. Low sodium is the single most common electrolyte disorder in people who drink excessively, and it plays a role in everything from nerve signaling to water balance. Low potassium can cause muscle weakness and, in serious cases, heart rhythm problems.
Plain water helps, but it won’t replace what you’ve lost. Drink an electrolyte solution, coconut water, or even broth. Sports drinks work too, though they tend to be high in sugar. Aim to drink steadily over several hours rather than forcing large amounts at once, which can trigger nausea. Rehydrating after alcohol can require roughly twice as much fluid as normal, so don’t stop at one glass.
Eat to Stabilize Blood Sugar
Alcohol directly suppresses your liver’s ability to produce glucose, the sugar your brain and muscles run on. This is why you might feel shaky, weak, foggy, or irritable the morning after. Your liver was busy processing alcohol instead of maintaining your blood sugar, and the result is a mild form of hypoglycemia that can linger even after the alcohol is gone.
Eating is one of the fastest ways to feel better. Focus on foods that release energy slowly: toast, oatmeal, bananas, rice, or eggs. These give your liver the raw materials to restore glucose levels without the crash that comes from sugary foods. If your stomach can’t handle a full meal, start small. A few crackers or a banana with peanut butter is enough to get the process started.
Be Gentle With Your Stomach
Binge drinking inflames the stomach lining, a condition called gastritis. That’s what causes the nausea, burning, and general abdominal misery. Mild gastritis typically resolves on its own, but you can help it along by choosing low-acidity, low-fat foods. Yogurt, which contains probiotics, can support your digestive tract. Green tea has some evidence behind it for reducing stomach irritation. Ginger, whether in tea or chewed raw, is a well-established remedy for nausea.
Avoid coffee on an empty stomach, spicy food, and acidic drinks like orange juice until your gut calms down. If you need an antacid, an over-the-counter option containing bismuth subsalicylate (the active ingredient in Pepto-Bismol) can reduce inflammation and discomfort in mild cases.
Be Careful With Pain Relievers
Reaching for a painkiller is instinctive, but the wrong one can cause real harm. Acetaminophen (Tylenol) is processed by your liver, which is already under strain from the alcohol. Studies on acetaminophen and alcohol show that people who drink heavily have a meaningfully higher risk of liver toxicity from acetaminophen compared to non-drinkers, even at the same dose. This isn’t a theoretical concern. It’s one of the most common causes of acute liver failure.
Ibuprofen (Advil, Motrin) or naproxen (Aleve) are generally considered safer choices after drinking, but they come with their own risk: they can worsen stomach irritation that alcohol already started. If you take one, eat something first and stick to the lowest effective dose. The honest best option is to wait it out with hydration and food if you can tolerate the headache.
Expect Poor Sleep, and Plan for It
Even though alcohol knocks you out quickly, the sleep you get after binge drinking is genuinely bad. Alcohol suppresses REM sleep, the phase your brain needs for memory consolidation and emotional regulation. In the first half of the night, you may sleep deeply, but the second half is fragmented, with more wakefulness and lighter sleep stages. This is why you might pass out hard at 1 a.m. and then lie awake at 4 a.m. feeling wired and anxious.
That anxiety has a biological basis. Alcohol amplifies the activity of your brain’s calming system (GABA) while suppressing its excitatory system (glutamate). When the alcohol wears off, those systems rebound in the opposite direction, leaving you in a state of heightened alertness and unease that some people call “hangxiety.” This imbalance corrects itself, usually within 12 to 24 hours, but in the meantime, rest is the best thing you can do. Even if you can’t fall back asleep, lying down in a dark room with your eyes closed gives your nervous system a chance to recalibrate. Napping later in the day can help recover some of the restorative sleep you missed.
Replenish Your B Vitamins
Heavy drinking depletes several vitamins, with B vitamins taking the hardest hit. Thiamine (B1), folate, and B12 are all reduced through a combination of poor absorption, altered metabolism, and increased excretion. You don’t need megadoses. A standard multivitamin contains about 150% of the recommended daily amount of 11 different compounds, including all the major B vitamins plus vitamins C and E. Taking one with food after a binge is a simple step that supports your body’s repair processes. Magnesium supplementation can also help, since magnesium drops alongside the other electrolytes.
Don’t Try to Sweat It Out
The idea that you can exercise away a hangover is a myth. Your body eliminates alcohol at a fixed rate of about 7 grams per hour, roughly one standard drink. Nothing speeds this up, not sweating, not coffee, not a cold shower. Exercise while you’re still processing alcohol compounds dehydration and puts extra strain on your cardiovascular system. People with any underlying heart issues face particular risk. If you want to move, a gentle walk in fresh air is fine, but save the intense workout for the next day.
A Realistic Recovery Timeline
At one drink per hour, someone who had 10 drinks finishing at midnight won’t be fully clear of alcohol until roughly 10 a.m. Hangover symptoms typically peak several hours after blood alcohol hits zero, because much of what you feel is your body’s inflammatory and neurochemical rebound, not the alcohol itself. For a heavy binge, expect to feel rough for 12 to 24 hours. Some people notice lingering fatigue, brain fog, or mild anxiety for up to 48 hours.
The practical recovery checklist is short: electrolyte fluids, easy-to-digest food, a multivitamin, rest, and time. Everything else is just waiting for your liver and brain to finish cleaning up.
