There’s no instant cure for a hangover, but you can significantly shorten your misery by targeting the specific things making you feel terrible: dehydration, low blood sugar, inflammation, and the toxic byproducts your liver is still processing. Your body clears roughly one standard drink per hour, so if you had eight drinks, the biological cleanup takes about eight hours from your last sip. You can’t speed that clock up, but you can address every symptom layered on top of it.
Why You Feel This Bad
When your liver breaks down alcohol, it first converts it into a compound called acetaldehyde, which is significantly more toxic than alcohol itself. Acetaldehyde gets further broken down into harmless acetic acid, but that second step takes time. While acetaldehyde lingers in your system, it triggers nausea, headache, and that overall “poisoned” feeling. Some people process acetaldehyde more slowly than others due to genetic differences in liver enzymes, which is why the same number of drinks can hit people very differently.
On top of that, alcohol is a diuretic. It suppresses a hormone that tells your kidneys to hold onto water, so you lose far more fluid than you take in. You also lose electrolytes (sodium, potassium, chloride) along with that fluid. Meanwhile, your liver prioritizes metabolizing alcohol over maintaining your blood sugar, which can leave glucose levels low enough to cause shakiness, fatigue, and brain fog. Every hangover symptom traces back to one of these mechanisms, and the fastest recovery means addressing all of them at once.
Rehydrate With Electrolytes, Not Just Water
Plain water helps, but it’s not the fastest option. You’ve lost electrolytes along with fluid, and replacing both at the same time helps your body absorb water more efficiently. Drinks like Pedialyte contain water, dextrose (a sugar that aids absorption), sodium, potassium, chloride, and zinc. Sports drinks like Gatorade have a similar profile, though typically with more sugar and fewer electrolytes. Coconut water is a decent natural alternative, with sodium, potassium, and manganese.
Start drinking fluids as soon as you wake up and keep sipping steadily rather than chugging a liter at once, which can worsen nausea. If your stomach can handle it, aim for at least 16 to 24 ounces in the first hour.
Eat to Stabilize Blood Sugar
Your liver deprioritized blood sugar regulation while it was busy with alcohol, and that deficit can persist for hours after your last drink. Eating is one of the single most effective things you can do for a hangover, especially if you went to bed without food. Complex carbohydrates like toast, oatmeal, or crackers provide steady glucose without spiking and crashing your blood sugar the way candy or juice would.
Eggs are a popular hangover food for a reason beyond tradition. They’re rich in an amino acid called L-cysteine, which supports liver function and may help your body process acetaldehyde. A cup of oatmeal provides about 227 mg of L-cysteine, and a serving of meat or fish contains even more (over 500 mg in a pork chop or tuna fillet). Whether these amounts meaningfully speed up acetaldehyde clearance in a real-world hangover is still uncertain, but eggs and oatmeal check multiple boxes: they’re gentle on the stomach, provide protein and carbs, and contain nutrients your body needs for recovery.
Bananas are another smart choice. They’re easy to eat when you feel awful and they’re loaded with potassium, one of the key electrolytes you’ve lost.
Choose the Right Pain Reliever
Headache is usually the symptom people most want gone. Your two main over-the-counter options are ibuprofen (Advil, Motrin) and acetaminophen (Tylenol), and the choice matters more than usual when alcohol is involved.
Acetaminophen is processed by the liver, and your liver is already under strain from alcohol metabolism. Overdosing on acetaminophen is the most common cause of acute liver failure, and alcohol increases that risk. If you take it, stay well under 2 grams for the day. Ibuprofen and other NSAIDs carry their own risk: they can irritate an already-inflamed stomach lining and, when combined with alcohol, put additional stress on the liver. Neither option is perfectly safe in this context, but ibuprofen is generally the more common recommendation for hangover headaches because it also reduces the inflammation driving many of your symptoms. Take it with food and water to protect your stomach.
Settle Your Stomach With Ginger
If nausea is your dominant symptom, ginger is one of the most reliable natural remedies. It’s been used for nausea relief for centuries, including specifically for hangovers. The active compounds in ginger root work on receptors in the digestive tract to calm nausea signals. Clinical studies on nausea from other causes (surgery, pregnancy, motion sickness) have found that doses between 250 mg and 1 gram per day, split into a few portions, are effective. There’s no evidence that taking more than 1 gram works any better.
The easiest ways to get it: brew fresh ginger slices in hot water for five minutes, drink ginger ale made with real ginger (check the label, since many brands use artificial flavoring), or chew on candied ginger. Ginger tea has the added benefit of contributing to your fluid intake.
What Actually Doesn’t Work
Coffee is tempting because you’re exhausted, but caffeine is another diuretic, which can worsen dehydration. A small cup probably won’t hurt if you drink extra water alongside it, but it won’t accelerate your recovery. If you’re sensitive to caffeine on an empty, irritated stomach, it can also make nausea worse.
“Hair of the dog,” or drinking more alcohol, delays your hangover rather than curing it. You’re essentially restarting the cycle your liver was trying to finish. It may temporarily blunt symptoms because alcohol numbs pain perception, but you’ll pay for it later, often with a worse hangover than the original.
IV drip services marketed for hangovers deliver saline and vitamins directly into your bloodstream. They do rehydrate you faster than drinking fluids, but there’s no strong evidence they resolve hangovers any better than oral rehydration combined with food and rest. They’re expensive and carry the small but real risks of any needle-based procedure.
Your Drinks Last Night Also Matter
Not all alcohol produces equal hangovers. Darker spirits like bourbon, brandy, and whiskey contain higher levels of congeners, which are chemical byproducts of fermentation that contribute to hangover severity. Red wine is also high in congeners. One study found that hangover severity scores were significantly worse after bourbon compared to vodka, even when participants reached the same blood alcohol level. Vodka and beer have the lowest congener levels.
This won’t help you today, but it’s useful for next time: choosing lighter-colored spirits or beer over dark liquor and red wine can meaningfully reduce how bad you feel the next morning.
The Fastest Realistic Recovery Plan
If you’re reading this while miserable, here’s the priority order. First, drink 16 to 24 ounces of an electrolyte beverage within the first hour of waking up. Second, eat something bland and carb-heavy as soon as your stomach allows it (toast, oatmeal, a banana). Third, take ibuprofen with that food if your headache is significant. Fourth, sip ginger tea if nausea lingers. Then rest. Sleep is when your body does its most efficient repair work, and if you can manage another hour or two of sleep after eating and hydrating, you’ll often wake up feeling dramatically better.
Most hangovers resolve within 24 hours. If you had a moderate night (four to six drinks), expect to feel noticeably better within six to eight hours of your last drink, assuming you hydrate and eat. A heavier night may take the full 24 hours. There’s no shortcut past the biological clock of roughly one drink cleared per hour, but stacking these strategies means you won’t be suffering through every minute of that timeline.
