Hangover symptoms peak once your body has fully processed the alcohol, meaning you typically feel worst right around the time your blood alcohol level hits zero. From there, symptoms can linger for 24 hours or longer. There’s no instant cure, but several strategies can meaningfully reduce how miserable you feel and help your body recover faster.
Why You Feel This Bad
A hangover isn’t just one thing going wrong. It’s several problems hitting at once: dehydration, inflammation, poor sleep, and a buildup of toxic byproducts from alcohol metabolism. Alcohol is a diuretic, so you’ve lost more fluid than you took in. Your immune system is triggering an inflammatory response. And your liver has been converting alcohol into acetaldehyde, a toxic compound that your body then has to break down further before it’s safe.
On top of all that, alcohol wrecks your sleep quality even if you were unconscious for eight hours. It suppresses the deep, slow-wave sleep your brain needs for restoration and memory. The result is that groggy, foggy feeling that no amount of time in bed seems to fix.
Rehydrate, Then Keep Hydrating
Water is the single most important thing to start with. Drink a full glass as soon as you’re awake, and keep sipping throughout the morning. If you were vomiting or sweating heavily, you’ve also lost electrolytes (sodium, potassium, magnesium), so a sports drink, coconut water, or even broth will help more than plain water alone. Don’t chug a liter all at once if your stomach is fragile. Steady, moderate sips work better.
Eat the Right Foods
Your instinct to eat eggs is a good one. Eggs are high in cysteine, an amino acid that helps your body break down acetaldehyde, the toxic byproduct your liver produces while metabolizing alcohol. In animal studies, cysteine dramatically improved survival rates when subjects were exposed to large amounts of acetaldehyde. Scrambled eggs, toast, and a banana make a solid hangover meal: protein and cysteine from the eggs, easy carbohydrates from the toast to stabilize blood sugar, and potassium from the banana to replace what you lost.
Alcohol also depletes B vitamins, particularly B1 (thiamine), which plays a key role in energy metabolism and brain function. Whole grains, nuts, and fortified cereals can help replenish those stores. If you have a B-complex supplement on hand, this is a reasonable time to take one.
Choose Your Pain Reliever Carefully
If you have a splitting headache, ibuprofen or aspirin can help with the inflammation driving it. But both can irritate your stomach lining, which is already inflamed from the alcohol. Take them with food, not on an empty stomach.
Avoid acetaminophen (Tylenol). Alcohol changes how your liver processes this drug, causing a toxic byproduct to accumulate in liver cells. The American College of Gastroenterology warns that people who drink regularly should avoid acetaminophen entirely, and even occasional drinkers should not take it while alcohol is still being processed. With a hangover, your liver is already working hard. Don’t add to its burden.
Rest, but Don’t Expect Great Sleep
If you can go back to sleep, do it. Your body did not get quality rest the night before, even if you slept for a long time. Alcohol specifically reduces slow-wave (deep) sleep while increasing the lightest stage of sleep, which is why you may have woken up multiple times or feel unrested despite a full night. A nap later in the day, once the alcohol is fully out of your system, will be more restorative than the sleep you got last night.
Skip the “Hair of the Dog”
Drinking more alcohol the next morning is one of the oldest hangover “remedies” in the world. Germans call it a “counter-beer,” Scandinavians call it a “repair beer,” and Italians have their own name for it. The logic sounds reasonable: if you feel bad because you stopped drinking, start again.
But a hangover is not the same as alcohol withdrawal. Withdrawal happens to people with chronic alcohol dependence. A hangover happens to anyone after a single bout of heavy drinking, and the mechanisms are different. Drinking more alcohol in the morning doesn’t fix the dehydration, the inflammation, or the acetaldehyde damage. It just delays the reckoning while adding more toxins for your liver to process. You’ll feel the original hangover later, possibly worse.
What Actually Helps, Hour by Hour
In the first hour or two after waking, focus on water, electrolytes, and a gentle meal. If your stomach can’t handle food yet, start with broth or a smoothie. Once you’ve eaten, take ibuprofen if the headache is severe.
By midday, you should be feeling somewhat better as your body clears the remaining toxins. Light movement, like a short walk outside, can improve circulation and mood without taxing your body. Avoid intense exercise; you’re dehydrated and your coordination may still be off.
Through the afternoon, continue eating small meals and drinking fluids. Symptoms typically resolve within 24 hours of onset, though particularly heavy drinking sessions can stretch that timeline. If you’re still feeling significantly ill after a full day, or if you experience confusion, seizures, or an inability to keep water down, that’s beyond a normal hangover.
Reduce Severity Next Time
What you drink matters almost as much as how much. Dark liquors like bourbon, brandy, cognac, and dark whiskey contain high levels of congeners, toxic byproducts of fermentation that include methanol. Your body breaks methanol down into formaldehyde and formic acid, which compound hangover misery. Clear spirits like vodka, gin, light rum, and white wine have significantly fewer congeners and tend to produce milder hangovers at equivalent alcohol levels.
Eating a substantial meal before drinking slows alcohol absorption. Alternating alcoholic drinks with water reduces total intake and offsets dehydration as you go. And paying attention to your pace matters more than any remedy the next morning. Most hangover suffering is proportional to how much you drank and how fast you drank it.
