The room is spinning. Your mouth feels like it’s been stuffed with dry cotton balls and your head is thumping in time with a heartbeat that feels way too loud. We’ve all been there. You wake up, squinting at the sunlight, and immediately start bargaining with the universe. You promise you’ll never drink again if this just stops. But honestly? The universe isn't listening. Biology is. Knowing what to do when you have a hangover isn't about magic spells or "hacker" supplements; it’s about managing the chemical mess you’ve made of your internal systems.
Alcohol is a diuretic. It forces your kidneys to release more water than they should, leading to that parched, shaky feeling. But it’s more than just dehydration. Your liver is currently working overtime to break down ethanol into acetaldehyde, a toxic byproduct that's actually significantly more poisonous than the alcohol itself. This stuff creates inflammation, messes with your blood sugar, and ruins your sleep quality. You aren't just "tired." You are technically experiencing a mild form of withdrawal and acute poisoning simultaneously.
The Hydration Myth vs. The Electrolyte Reality
Everyone tells you to drink water. Obviously. But if you just chug two liters of plain tap water, you’re basically just diluting the few remaining minerals in your system. You need salts. When you're looking for what to do when you have a hangover, your first stop should be sodium, potassium, and magnesium. This is why Pedialyte or Liquid I.V. became cult favorites for adults. They aren't just for kids with the flu. They help your cells actually absorb the water you're drinking.
Don’t drink a giant coffee immediately. I know, it’s tempting. You have a meeting at 10:00 AM and you feel like a zombie. However, caffeine is another diuretic. It might give you a temporary jolt, but it can also narrow the blood vessels in your brain, potentially making that "icepick through the eye" headache even worse. If you must have caffeine, wait until you’ve finished at least 20 ounces of an electrolyte-heavy drink. Small sips.
Try a bouillon cube in hot water. It sounds gross when you’re nauseous, but the salt and the warmth can settle a stomach better than a cold Gatorade sometimes. Plus, it replaces the sodium you lost while running to the bathroom every twenty minutes the night before.

Why "Hair of the Dog" Is a Terrible Idea
We need to talk about the Bloody Mary. People swear by it. "Just one drink to take the edge off," they say. Here is the science of why that is a trap. Hangovers start when your blood alcohol content (BAC) hits zero. By drinking more, you’re just raising that BAC again. You aren't curing the hangover; you’re just hitting the snooze button on it. Once that morning drink wears off, the hangover will return, often with a vengeance because your liver is now even more exhausted.
Acetaldehyde is the enemy. Your body uses a substance called glutathione to break it down. When you drink, you burn through your glutathione stores fast. Adding more alcohol to the mix just keeps those stores depleted. You’re essentially just delaying the inevitable crash.
The Breakfast Debate: Grease vs. Science
You’re craving a massive, dripping bacon egg and cheese. Part of that is your brain hunting for dopamine. Another part is your body screaming for calories because alcohol causes your blood sugar to plummet. While a heavy breakfast feels like a rite of passage, it might actually make you feel worse if your stomach lining is irritated. Alcohol increases acid production in your stomach. Dumping a pile of grease on top of that can trigger acid reflux or more nausea.
Go for eggs. Specifically, eggs contain an amino acid called cysteine. Cysteine helps break down that nasty acetaldehyde we keep talking about. It’s one of the few foods that actually tackles the chemistry of the hangover rather than just masking the symptoms. Pair it with a banana for the potassium and maybe some whole-grain toast to stabilize your blood sugar without the grease-induced lethargy.

The Truth About Painkillers
Be very careful here. This is where people actually get into trouble.
- Acetaminophen (Tylenol): Do not touch it. Never. Your liver is already stressed out from processing the alcohol. Tylenol is also processed by the liver. Combining the two can lead to serious liver damage or even failure in extreme cases. It’s not worth the risk.
- Ibuprofen (Advil/Motrin) or Naproxen (Aleve): These are better for the headache, but they are "NSAIDS." They can be very harsh on your stomach lining, which is already irritated by the booze. If you take these, eat something small first.
Sleep Is the Only Real Healer
You probably slept for eight hours, but it wasn't good sleep. Alcohol inhibits REM sleep. You spent the night tossing, turning, and sweating. Your brain didn't get the chance to "clean" itself like it usually does. This is why you feel "brain fog." If you have the luxury, take a 90-minute nap in the afternoon. That’s roughly the length of one full sleep cycle.
Interestingly, light exposure matters. If you can manage to sit outside for ten minutes, the natural light can help reset your circadian rhythm, which the alcohol completely threw out of whack. Don't stare at the sun—your eyes are likely photosensitive today—but get some ambient daylight.
What to Do When You Have a Hangover: Subtle Tricks
Try ginger. Real ginger, not the high-fructose corn syrup ginger ale that has 0% actual root in it. Ginger is a potent anti-inflammatory and is scientifically proven to reduce nausea. Chew on a piece of candied ginger or steep some fresh slices in hot water.

Check your B vitamins. Alcohol depletes B-complex vitamins, which are essential for energy metabolism. Taking a B-complex supplement (or eating some nutritional yeast or fortified cereal) can help clear the mental fog. It won't be an instant fix, but it supports the recovery process over several hours.
Some people swear by honey. There’s actually some evidence that the fructose in honey helps your body metabolize alcohol slightly faster. A spoonful of honey on toast isn't a "cure," but it’s a gentle way to get sugar into your bloodstream without causing a massive spike and crash.
The Congener Factor
If you’re wondering why your hangover feels particularly demonic, look at what you drank. Darker liquors—like bourbon, brandy, and red wine—contain more "congeners." These are impurities produced during the fermentation process. Methanol is a common congener found in dark spirits, and it breaks down into formaldehyde. Yes, the stuff they use for embalming. If you drank cheap tequila or aged whiskey, your body is dealing with a much more complex chemical cocktail than if you’d stuck to vodka or gin. This doesn't change what you should do now, but it explains why your head feels like it’s in a vice.
Actionable Recovery Steps
Instead of panicking, follow this sequence to get back to being a human being:
- Immediate Rehydration: Drink 16 ounces of water with an electrolyte tablet or a pinch of sea salt and a squeeze of lemon. Do not chug; sip it over 15 minutes.
- Targeted Nutrition: Eat two eggs (poached or scrambled, not fried in heavy oil) and a banana. This provides cysteine and potassium.
- Stomach Settling: If you feel nauseous, drink hot ginger tea. Avoid coffee for at least the first two hours after waking up.
- Strategic Medication: If the headache is unbearable, take 200mg of Ibuprofen, but only after you have some food in your stomach. Avoid Tylenol entirely.
- Low-Intensity Movement: If you can walk for 10 minutes, do it. It increases circulation and helps your body process toxins faster. Don't try to "sweat it out" with a heavy workout; you're too dehydrated for that.
- The 90-Minute Nap: If your schedule allows, a mid-afternoon nap will do more for your cognitive function than any energy drink.
A hangover is basically a mini-illness. You wouldn't expect to "biohack" your way out of a fever in twenty minutes, so don't expect to do that here. Give your liver the resources it needs—water, minerals, and time—and stop making it do extra work. By the time the sun goes down, you'll likely feel 80% better. Just remember this feeling the next time someone offers you "one last round" at 1:00 AM.
