You woke up and the light is too loud. Your mouth feels like it’s been stuffed with cotton balls and sawdust, and there is a rhythmic drumming behind your eyes that definitely wasn't there last night. It’s the classic biological tax for a night out. If you’re searching for what to do if you have a hangover, you’re likely looking for a magic pill or a secret ritual to make the nausea stop immediately.
Honesty is best here: there isn't a "cure" in the clinical sense. Alcohol is a diuretic and a toxin. Your liver is currently working overtime to process acetaldehyde, a byproduct of ethanol metabolism that is significantly more toxic than the alcohol itself. While you wait for your internal chemistry to balance out, you can definitely mitigate the damage.
The Immediate Response: Hydration and Electrolytes
Stop reaching for the coffee. Seriously. While the caffeine might provide a temporary jolt to your foggy brain, it’s also a diuretic. It will push more fluid out of a body that is already desperately parched. Alcohol inhibits the antidiuretic hormone (ADH), which is why you spend half the night in the bathroom when you drink. By the time you wake up, your brain has physically shrunk slightly due to dehydration, pulling on the membranes connecting it to the skull. That’s the headache.
You need water, but water alone isn't always enough if your mineral levels are tanked. Go for an oral rehydration solution. Something like Pedialyte or Liquid I.V. works because it uses the sodium-glucose cotransport system. Basically, a specific ratio of salt and sugar helps your intestines absorb water faster. If you don't have those, a glass of water with a pinch of salt and a squeeze of lemon is a solid DIY fix.
Don't chug a gallon in thirty seconds. Your stomach is likely irritated—the lining of your gut (the gastric mucosa) is inflamed. Sip slowly. If you vomit, you’re losing even more electrolytes, specifically potassium and magnesium. A banana is your best friend here. It’s gentle on the stomach and replaces that lost potassium, which helps with the shaky, weak-muscle feeling.
What to Do if You Have a Hangover and Can’t Stop the Room Spinning
The technical term for the world tilting is "positional alcohol nystagmus." It happens because alcohol changes the density of the fluid in your inner ear (the cupula). When the density of that fluid doesn't match the surrounding tissue, your brain gets confused about which way is up.
One old-school trick that actually has some physical merit is putting one foot on the floor while lying in bed. It gives your brain a grounded, tactile reference point to fight the internal sensory conflict.

Should you take painkillers?
This is where people usually mess up. Avoid Acetaminophen (Tylenol) at all costs. Your liver is busy processing the remnants of last night’s tequila. Acetaminophen is also processed by the liver. When combined with alcohol, it can trigger the production of toxic metabolites that cause permanent liver damage. It’s a dangerous gamble for a temporary headache fix.
If your stomach can handle it, an NSAID like Ibuprofen (Advil) or Naproxen (Aleve) is a better bet. These address the inflammation that is a primary driver of hangover symptoms. However, be careful—NSAIDs can be harsh on an already irritated stomach lining. If you’re feeling "acidic" or nauseous, maybe skip the pills until you've managed to keep some toast down.
The Myth of the Greasy Breakfast
Everyone has that one friend who swears by a triple-bacon cheeseburger at 9:00 AM.
The logic is that the grease "soaks up" the alcohol. This is biologically impossible. The alcohol is already in your bloodstream or has been processed; grease isn't a sponge. In reality, a heavy, fatty meal might actually make things worse by triggering acid reflux or slowing down gastric emptying.
What you actually need are complex carbohydrates. Your blood sugar is likely low because the liver is too busy dealing with toxins to maintain glucose levels. Toast, crackers, or a plain bagel are the move. They provide a steady release of energy without offending your digestive system. Eggs are also a powerhouse. They contain an amino acid called cysteine. Cysteine helps break down acetaldehyde, the nasty stuff that makes you feel like garbage. A couple of poached eggs on dry toast is the "expert" version of the greasy fry-up.
The Science of Congeners
Why does a red wine hangover feel different than a vodka hangover? It’s all about congeners. These are chemical byproducts of the fermentation process, like tannins, methanol, and acetone. Darker liquors—think bourbon, brandy, and red wine—have significantly higher levels of congeners than clear spirits like vodka or gin.

A study in the journal Alcoholism: Clinical and Experimental Research found that while people felt equally "drunk" on vodka vs. bourbon, the bourbon group reported significantly worse hangovers the next day. If you’re currently suffering from a red wine headache, you’re dealing with a combination of dehydration and a mild inflammatory response to these impurities.
Moving Your Body (Gently)
You might have heard people talk about "sweating it out."
You cannot sweat out a hangover. Only about 1% to 10% of alcohol leaves the body through sweat, breath, or urine; the rest is metabolic work performed by your liver. Going for a high-intensity run when you're dehydrated is a recipe for fainting or heat stroke.
However, light movement can help. A slow walk in the fresh air increases your oxygen intake and boosts blood flow, which can help clear that mental fog. Just stay out of the direct sun. Your skin can be more sensitive, and the heat will just dehydrate you further.
The "Hair of the Dog" Trap
The idea of drinking more alcohol to cure a hangover is a classic case of delaying the inevitable. It works momentarily because you’re essentially dulling your senses again and raising your blood alcohol level back up, which masks the withdrawal symptoms.
Yes, a hangover is technically a mini-withdrawal. When you drink, your brain suppresses glutamate (an excitatory neurotransmitter) and boosts GABA (a calming one). When the alcohol wears off, your brain overcompensates by flooding your system with glutamate. This is why you feel anxious, jittery, and sensitive to light. Having a Mimosa or a Bloody Mary just kicks the can down the road. You’ll have to pay the bill eventually, and usually, the second crash is worse.

Practical Steps to Take Right Now
If you are currently in the thick of it, follow this loose protocol. Don't worry about the order perfectly, just do what you can.
- Drink 16 ounces of an electrolyte drink. If you don't have one, go for water with a tiny bit of salt.
- Eat something bland. A banana or a piece of sourdough toast.
- Take a cool shower. It won't sober you up, but the sensory shift can help snap you out of the lethargy.
- Try Ginger. If you're nauseous, ginger is a scientifically backed anti-emetic. Ginger tea or even a high-quality ginger ale (with real ginger) can settle the stomach.
- Sleep. If your schedule allows, a 90-minute nap (one full sleep cycle) can do wonders for the brain's "trash-clearing" glymphatic system.
- Darkness. Close the curtains. Your pupils are likely dilated and struggling to regulate light, which is contributing to the headache.
Looking Forward: How to Not Do This Again
Next time, the "buffer" method is your best defense. This isn't just about drinking a glass of water at the end of the night. It's about drinking one glass of water for every single alcoholic beverage you consume. This forces you to slow down your intake and keeps your hydration levels stable in real-time.
Also, eat a meal high in protein and healthy fats before the first drink. Fat slows down the absorption of alcohol into the small intestine, which prevents that massive spike in blood alcohol concentration that leads to the worst hangovers.
Ultimately, the only 100% effective way to avoid a hangover is to not drink, or to stay well within the "moderate" range. But since you're already here, focus on time and hydration. Your liver is a remarkably resilient organ. It’s doing its job; you just need to give it the fluids and the quiet environment it needs to finish the cleanup.
Key Takeaways for Recovery
- Avoid Tylenol. Use Ibuprofen if you must, but be wary of your stomach.
- Prioritize salts over plain water. Potassium and sodium are your priority.
- Skip the caffeine. It's a false sense of security that leads to a harder crash.
- Amino acids are key. Eggs and oats provide the building blocks your liver needs to process toxins.
- Be patient. Most hangovers peak about 12 to 14 hours after your blood alcohol level hits zero.
Go easy on yourself. The anxiety you’re feeling—often called "hangxiety"—is a chemical imbalance, not a reflection of your character. Drink your water, stay in the shade, and wait for the glutamate storm to pass.
