The fastest way to ease a bad hangover is to rehydrate, eat something, take the right pain reliever, and sleep. There’s no instant cure, but you can shorten the misery and blunt the worst symptoms within a few hours. Hangover symptoms peak once your blood alcohol level drops back to zero and can last 24 hours or longer, so the sooner you start addressing them, the better.
Why You Feel This Bad
When your liver processes alcohol, it first converts it into a toxic compound called acetaldehyde before breaking that down further into harmless substances. If you drank more than your liver could keep up with, acetaldehyde built up in your system and damaged cells along the way. People who genetically produce less of the enzyme that clears acetaldehyde (common among East Asians) tend to get significantly worse hangovers for exactly this reason.
Alcohol also triggers inflammation throughout your body, suppresses a hormone that helps your kidneys retain water (which is why you urinate so much while drinking), and irritates your stomach lining. On top of that, your brain chemistry is rebounding. Alcohol suppresses a stimulating brain chemical called glutamine while you’re drinking, and once you stop, your brain overproduces it to compensate. That glutamine rebound is why you feel restless, anxious, and unable to sleep deeply even though you’re exhausted.
Rehydrate Aggressively
Dehydration drives the headache, dizziness, and fatigue. Water helps, but drinks with electrolytes (sodium, potassium, magnesium) work faster because alcohol flushed those out along with the water. Sports drinks, coconut water, or even a pinch of salt in water with a squeeze of citrus will do the job. Aim to drink at least 16 to 24 ounces within the first hour of waking up, then keep sipping steadily.
Broth or soup is another excellent option because it delivers sodium, water, and calories all at once. If you’re nauseous, take small sips rather than gulping. Cold fluids are often easier to tolerate on a churning stomach.
Eat Something, Even If You Don’t Want To
Your blood sugar is likely low, which contributes to shakiness, weakness, and irritability. Simple carbohydrates like toast, crackers, or bananas will bring it back up quickly. Eggs are a popular hangover food for good reason: they contain an amino acid called cysteine that helps your body process leftover acetaldehyde.
There’s also some evidence that fructose, the sugar found in fruit and fruit juice, modestly speeds up alcohol metabolism. A study published in The Lancet found that large doses of fructose increased the rate at which the body cleared alcohol. You probably won’t notice a dramatic difference from a glass of orange juice, but it provides hydration, sugar, and potassium all at once, which makes it a solid choice.
Avoid greasy, heavy meals right away if your stomach is already upset. They can make nausea worse. Start bland, then eat more substantially once your stomach settles.
Choose the Right Pain Reliever
A standard dose of ibuprofen or naproxen can help with headache and body aches. Both are anti-inflammatory, which targets the inflammation alcohol triggered. However, they can irritate an already-sensitive stomach, so take them with food and water, not on an empty stomach.
Avoid acetaminophen (Tylenol) when you’re hungover. The combination of acetaminophen and alcohol can cause serious liver damage because your liver is already working hard to clear the alcohol byproducts. This is one of the most important things to know about hangover management. Aspirin is another option, but it carries the same stomach irritation risk as ibuprofen.
Be Careful With Coffee
Caffeine can help with the headache. It’s a central nervous system stimulant that constricts blood vessels and is genuinely useful for treating headaches. But it also raises your heart rate and blood pressure, acts as a diuretic, and can make anxiety and jitteriness worse. If you’re already dehydrated, shaky, and feeling your heart pound, a large coffee may amplify those symptoms.
If you’re a regular coffee drinker, a small cup can prevent a caffeine withdrawal headache from piling on top of your hangover. Just match every cup of coffee with at least an equal amount of water.
Sleep as Much as You Can
Alcohol wrecks sleep quality. Even if you were in bed for eight hours, you likely spent much of that time in lighter, fragmented sleep stages. The glutamine rebound makes this worse by keeping your brain in a stimulated state. The fatigue and brain fog you’re feeling are partly from poor sleep, not just from the alcohol itself.
If your schedule allows it, go back to sleep after hydrating and eating something small. A few hours of genuine rest can do more than any supplement. Your body clears the remaining toxins and inflammation faster when you’re sleeping.
What Probably Won’t Help
“Hair of the Dog”
Drinking more alcohol the next morning does temporarily reduce symptoms, and there’s a real chemical reason for it. Some hangover misery comes from methanol, a toxic byproduct found in many drinks. Your liver prioritizes processing ethanol (regular alcohol) first, and only converts methanol into its more harmful byproduct, formaldehyde, once the ethanol is gone. A morning drink supplies more ethanol, which delays methanol processing and lets your body excrete it harmlessly in urine instead.
The problem is obvious: you’re just postponing the hangover and adding more alcohol for your liver to deal with. This strategy also builds a dangerous habit pattern over time.
Hangover Supplements
The supplement market is full of products claiming to cure hangovers, including formulas with prickly pear, red ginseng, artichoke extract, clove bud extract, and various vitamin blends. A systematic review from King’s College London evaluated over 20 of these remedies and found that all the evidence was “very low quality,” typically due to poor study design or imprecise measurements. Some showed statistically significant improvements in individual symptoms, but none had convincing, replicable proof that they work.
That doesn’t mean they’re all useless. It means no one has proven any of them reliably enough to recommend. Your money is better spent on electrolyte drinks and real food.
Prevent the Next One
The type of alcohol you drink matters. Darker spirits like bourbon, brandy, and whiskey contain higher levels of compounds called congeners, which are byproducts of fermentation and distilling. Research has consistently shown that bourbon produces worse hangovers than vodka at the same blood alcohol level. Red wine and brandy also contain higher concentrations of methanol compared to beer and vodka. If you’re prone to bad hangovers, lighter-colored drinks are a meaningful advantage.
Pacing and food make the biggest difference. Eating a substantial meal before drinking slows alcohol absorption dramatically. Alternating each alcoholic drink with a glass of water reduces total consumption and keeps you hydrated throughout the night. And the most reliable prevention is simply drinking less: hangover severity scales directly with the amount of alcohol consumed, and there’s no trick that fully overcomes a high dose.
