The best hangover remedy is a combination of rehydration, food, rest, and the right pain reliever. There’s no single cure that eliminates a hangover instantly, but several strategies backed by evidence can shorten your misery and ease the worst symptoms. Most hangovers last about 12 hours from the time you wake up, with symptoms peaking roughly 14 hours after your last drink before declining rapidly. Here’s what actually helps.
Rehydrate With Electrolytes, Not Just Water
Alcohol is a diuretic, meaning it pulls fluid and minerals out of your body faster than normal. Replacing what you lost is the single most important step. Plain water helps restore fluid volume, but it doesn’t contain electrolytes like sodium and potassium, which your body also shed overnight. An oral rehydration solution like Pedialyte outperforms both water and sports drinks because it delivers higher levels of sodium and potassium without the excess sugar that can upset an already sensitive stomach.
Sports drinks fall somewhere in the middle. They replace some electrolytes, but their higher sugar content can aggravate nausea. If all you have is water, drink it. It’s far better than nothing. But if you can grab an electrolyte drink, you’ll notice a faster improvement in symptoms like headache, dizziness, and fatigue. Aim to sip steadily rather than gulping a large amount at once, which can trigger more nausea.
Eat Before and After Drinking
Your liver prioritizes breaking down alcohol over maintaining your blood sugar. When you drink without eating, this can cause a significant blood sugar drop, which contributes to the shakiness, weakness, and brain fog that make hangovers feel so awful. Liquid sugars (juice, soda) get absorbed too quickly to provide lasting protection. Solid food, on the other hand, digests gradually and keeps your blood sugar more stable.
The morning after, reach for complex carbohydrates and protein. Toast, oatmeal, eggs, or a simple breakfast burrito all work well. Eggs are a particularly popular hangover food because they contain an amino acid called L-cysteine, which supports liver function and may help your body clear acetaldehyde, the toxic byproduct your liver creates as it processes alcohol. The science on L-cysteine supplements as a hangover cure is limited, but eating whole eggs gives you protein, fat, and this amino acid together, which is a solid recovery meal regardless.
Bananas are another good choice because they’re rich in potassium, easy on the stomach, and provide quick energy.
Choose the Right Pain Reliever
A standard dose of ibuprofen (Advil, Motrin) or aspirin can ease a hangover headache. Both are anti-inflammatory, which helps because alcohol triggers widespread inflammation. The trade-off is that both can irritate your stomach lining, and your stomach is already irritated from the alcohol. If your hangover leans more toward nausea than headache, you may want to wait until you’ve eaten something before taking either one.
Avoid acetaminophen (Tylenol) when you’re hungover. Your liver is already working overtime to process alcohol, and acetaminophen adds to that burden. The FDA specifically warns that people who drink three or more alcoholic beverages a day should talk to a doctor before using acetaminophen due to the risk of liver damage. On a hangover morning, your liver hasn’t finished clearing last night’s alcohol, so ibuprofen is the safer choice.
Prickly Pear Extract May Help
One supplement with actual clinical trial data behind it is prickly pear extract. In a randomized, double-blind trial published in JAMA Internal Medicine, 64 volunteers took either prickly pear extract or a placebo five hours before drinking. The extract significantly reduced three symptoms: nausea, dry mouth, and loss of appetite. More notably, the risk of a severe hangover was cut roughly in half.
The overall symptom score improved, though not quite to the level of statistical significance. This isn’t a miracle cure, but it’s one of the few supplements with credible evidence showing a real effect. The catch is you need to take it before you drink, not the morning after.
What You Drink Matters
Not all alcohol produces equal hangovers. Darker liquors like bourbon, whiskey, and brandy contain higher levels of congeners, which are trace chemicals produced during fermentation. These congeners contribute directly to hangover severity. One well-known study found that bourbon produced significantly worse hangovers than vodka, even when subjects drank the same amount of alcohol. Beer, being generally darker and higher in congeners than clear spirits, also tends to produce rougher mornings.
If you know you’re prone to hangovers, sticking with clear spirits like vodka or gin (mixed with non-sugary mixers) can meaningfully reduce how bad you feel the next day. This won’t prevent a hangover from heavy drinking, but it shifts the odds in your favor.
The Recovery Timeline
Hangover symptoms begin as your blood alcohol concentration drops toward zero, which is why you typically feel fine while still buzzed and terrible when you wake up. From the time you stop drinking, the average hangover lasts about 18 hours. For most people, that translates to roughly 12 hours from waking. Symptoms tend to peak around 14 hours after your last drink, then decline fairly rapidly. By 21 hours post-drinking, most people feel close to normal.
Dehydration symptoms respond fastest to treatment. Drinking fluids can ease headache, dizziness, and dry mouth within an hour or two. Other symptoms, particularly fatigue, nausea, and mental fog, take longer because they depend on your body fully metabolizing the alcohol and its byproducts. That process simply takes time, and no remedy can speed it up dramatically.
A Practical Hangover Recovery Plan
Combining these strategies gives you the best shot at a shorter, milder hangover:
- Immediately on waking: Drink 16 to 20 ounces of an electrolyte solution like Pedialyte, or alternate water with a low-sugar sports drink.
- Within the first hour: Eat a meal with complex carbs and protein. Eggs, toast, and a banana cover most of your bases.
- For headache: Take ibuprofen with food. Avoid acetaminophen.
- Throughout the day: Continue sipping fluids and eating small meals. Rest when you can.
The honest truth is that time does most of the heavy lifting. But staying hydrated, fed, and choosing the right pain reliever can take the edge off those 12 hours considerably.
