There’s no instant cure for a hangover, but you can speed up recovery by addressing the specific things alcohol did to your body: it dehydrated you, disrupted your blood sugar, triggered inflammation, and left behind irritating byproducts your liver is still processing. The fastest path to feeling better combines rehydration, the right food, and a few strategic choices about what to avoid.
Why You Feel This Bad
A hangover isn’t just dehydration, though that’s part of it. Alcohol suppresses a hormone that tells your kidneys to hold onto water, so you lose far more fluid than you took in. But the headache, nausea, fatigue, and brain fog come from multiple sources working together.
Your liver breaks alcohol down in stages. First it converts ethanol into a toxic compound called acetaldehyde, then into acetate. Acetate appears to directly trigger headache pain. Meanwhile, your immune system reacts to the alcohol itself by releasing inflammatory signaling molecules, the same ones involved in feeling achy and run-down when you’re sick. On top of all that, alcohol tanks your blood sugar by interfering with your liver’s ability to release stored glucose. That’s where the shakiness, weakness, and difficulty concentrating come from.
One counterintuitive finding: people who metabolize alcohol faster tend to have less severe hangovers. Because ethanol (unlike its breakdown products) crosses into the brain, the longer it lingers in your system, the worse you feel the next day. This is partly why hangovers get worse with age, as your liver slows down.
Rehydrate With More Than Water
Water helps, but it’s not the fastest route to rehydration. Alcohol depletes electrolytes like sodium, potassium, and chloride, which your body needs to actually absorb and retain the fluid you’re drinking. Plain water passes through more quickly without those minerals present.
An oral rehydration solution like Pedialyte works better than either water or sports drinks. It contains a precise ratio of sugar and salt that pulls fluid into your bloodstream faster than water alone, with two to three times more electrolytes and about 25 to 50% less sugar than most sports drinks. That lower sugar content matters because your body works harder to digest sugary drinks, slowing fluid absorption and potentially upsetting your already sensitive stomach. If you don’t have Pedialyte on hand, broth is a solid alternative since it’s rich in sodium and easy on the stomach. Coconut water is another decent option for potassium.
Aim to drink steadily rather than chugging large amounts at once, which can trigger nausea.
Eat the Right Foods
Your blood sugar is likely low, and eating is one of the fastest ways to feel noticeably better. Bland foods with complex carbohydrates, like toast, crackers, or oatmeal, stabilize blood sugar without aggravating nausea. Bananas are useful because they replace potassium. Eggs contain an amino acid that helps your liver process alcohol’s byproducts.
Avoid greasy, heavy meals. The idea that a big breakfast “soaks up” alcohol is a myth. By the time you’re hungover, the alcohol has already been absorbed. Heavy food just makes your digestive system work harder when it’s already irritated. Start small and bland, then eat more as your stomach settles.
Be Careful With Pain Relievers
Reaching for a painkiller is tempting, but your choice matters. Acetaminophen (Tylenol) is processed by your liver, which is already under strain from metabolizing alcohol. The combination increases the risk of liver damage, and acetaminophen overdose is the most common cause of acute liver failure. Skip it while you’re hungover.
Ibuprofen (Advil, Motrin) or naproxen (Aleve) are generally the safer option for hangover headaches since they target the inflammation driving your symptoms. That said, these can irritate your stomach lining, which alcohol has already inflamed. Take them with food and water, not on an empty stomach.
Skip the Coffee (For Now)
Coffee feels like the obvious move, but caffeine narrows blood vessels and raises blood pressure, which can amplify the pounding headache you already have. It’s also a mild diuretic, working against your rehydration efforts. If you’re a daily coffee drinker and skipping it would give you a caffeine withdrawal headache on top of your hangover, a small amount is reasonable. But don’t rely on it as a hangover fix.
Why “Hair of the Dog” Is a Trap
Drinking more alcohol the next morning can temporarily mask hangover symptoms, which is why the advice persists. But a hangover and alcohol withdrawal are not the same thing. Withdrawal happens in people with chronic alcohol dependence. For everyone else, a morning drink simply delays the hangover while adding more toxic byproducts for your liver to process. You’ll feel worse later, not better.
What Actually Helps Right Now
If you’re currently hungover and looking for a plan, here’s the practical sequence:
- Drink an electrolyte solution like Pedialyte, broth, or diluted sports drinks. Sip steadily over an hour or two.
- Eat something bland as soon as your stomach can handle it. Toast, crackers, a banana, or plain rice.
- Take ibuprofen with food if your headache is severe. Avoid acetaminophen.
- Sleep more if you can. Alcohol disrupts sleep quality even when you’re unconscious for enough hours. Your body does most of its recovery work during sleep, and a nap can cut hours off your hangover.
- Go easy on caffeine. If you need it, keep it to one small cup with plenty of water alongside.
How to Prevent the Next One
The only guaranteed prevention is drinking less, but a few strategies genuinely reduce severity. What you drink matters. Darker alcohols like bourbon, whiskey, and red wine contain higher levels of congeners, chemical byproducts of fermentation that make hangovers worse. One study found that bourbon produced significantly more severe hangovers than vodka at the same alcohol dose. Lighter-colored spirits like vodka, gin, and white rum have far fewer congeners.
Eating a substantial meal before drinking slows alcohol absorption, giving your liver more time to process each drink. Alternating alcoholic drinks with water throughout the night reduces total alcohol intake and keeps you more hydrated. And pacing yourself to roughly one drink per hour gives your body a chance to metabolize each serving before the next one arrives, which directly reduces the buildup of toxic byproducts that cause morning misery.
