You wake up. The light hitting the wall feels like a personal insult. Your mouth is dry, your head is thumping in time with your pulse, and you’re pretty sure you’ve been poisoned. You haven't, obviously. You just had a few too many drinks. But now you’re staring at your phone, squinting through the glare, wondering how can you get over a hangover before your 10:00 AM meeting starts.
Most people reach for the wrong things. They want a magic pill or a "hair of the dog" solution that actually just kicks the can down the road.
Alcohol is a diuretic. It suppresses vasopressin, the hormone that tells your kidneys to hold onto water. When you stop producing it, you pee out more than you take in. This leads to that classic shriveled-brain feeling. But dehydration is only about 30% of the problem. The rest is a messy cocktail of inflammation, acetaldehyde buildup, and plummeting blood sugar.

The Science of Why You Feel Like Trash
When your liver processes ethanol, it uses an enzyme called alcohol dehydrogenase to turn it into acetaldehyde. This stuff is toxic. It’s actually significantly more toxic than the alcohol itself. Usually, your body handles it with glutathione, but if you drank enough to be reading this, you’ve probably tapped out your glutathione stores. Your body is basically stuck in a biological bottleneck.
Then there’s the stomach lining. Alcohol is an irritant. It makes your stomach produce more acid and slows down your digestion. This is why you feel nauseous. It’s not just "grossness"; it’s actual gastric distress.
Forget the Greasy Spoon Myth
Everyone says to eat a giant, greasy breakfast. Honestly? That's probably a mistake if you're already feeling sick. Fat is hard to digest. If your stomach is already irritated, tossing a pile of bacon and hash browns onto it is like pouring gasoline on a flickering fire. You want simple carbohydrates.
Think about blood sugar for a second. Alcohol messes with your liver's ability to release glucose into the bloodstream. This is why you feel shaky and weak. A piece of toast or a banana is actually way more effective at stabilizing you than a five-pound burrito.
How Can You Get Over a Hangover Using Real Science
The first step is always rehydration, but water isn't enough. You need electrolytes—sodium, potassium, and magnesium. This is why Pedialyte or liquid IV products have become the go-to for anyone over thirty. They restore the osmotic balance in your cells way faster than plain tap water.
Watch out for the Tylenol trap. This is the most dangerous mistake people make. Acetaminophen (Tylenol) is processed by the same pathways in the liver as alcohol. If you have alcohol still in your system—which you do, if you’re hungover—taking Tylenol can lead to serious liver inflammation or damage. Stick to ibuprofen or aspirin. They are NSAIDs. They target the inflammation that’s causing your headache without putting that extra load on your liver.
The Congener Problem
Ever notice how red wine or bourbon leaves you feeling worse than vodka? That's because of congeners. These are chemical byproducts of the fermentation process like methanol, tannins, and acetone. Darker liquors have way more of them. Methanol is particularly nasty because your body breaks it down into formaldehyde. Yes, the stuff they use for embalming. If you’re wondering how can you get over a hangover more effectively in the future, maybe stick to the clear stuff.

Dealing With the "Hangxiety"
It's not just physical. The "Sunday Scaries" or "Hangxiety" is a real physiological response. Alcohol is a central nervous system depressant. To counter it, your brain ramps up glutamate (an excitatory neurotransmitter) and turns down GABA (the chill-out chemical). When the alcohol leaves, your brain is still stuck in high-alert mode.
You feel edgy. You’re paranoid about what you said last night. Your heart is racing.
None of the physical cures will fix this part. The only thing that helps is time and perhaps a bit of magnesium to help the nervous system settle down. Dr. George Koob, the director of the National Institute on Alcohol Abuse and Alcoholism (NIAAA), has often spoken about this "rebound effect." Your brain is essentially trying to find its equilibrium again, and that process is inherently uncomfortable.
Sleep is a Lie
You might have "slept" for eight hours, but it wasn't good sleep. Alcohol destroys REM cycles. You spent the night in a light, fragmented stupor. This is why you feel like you've been hit by a truck even if you stayed in bed until noon. You can't "catch up" on that lost REM sleep in one morning, but a twenty-minute nap in the afternoon can sometimes reset your cognitive fog just enough to function.
What Actually Works (and What Doesn't)
- Do take B-Vitamins. Alcohol depletes them rapidly. A B-complex supplement can help with the metabolic process of clearing toxins.
- Don't do "Hair of the Dog." All you're doing is raising your blood alcohol level again. The symptoms will just come back twice as hard once you sober up. It’s a temporary mask, not a cure.
- Do drink ginger tea. Ginger is one of the few natural substances with actual clinical backing for reducing nausea. It stimulates saliva and gastric juices, helping move things through your system.
- Don't bother with expensive "hangover patches." Most of them don't have enough active ingredients to make a dent in the systemic inflammation you're facing.
The real answer to how can you get over a hangover is a boring one: Metabolism. You cannot speed up the liver's processing of alcohol. It happens at a fixed rate of roughly one standard drink per hour. No amount of cold showers or black coffee will change that internal clock. Coffee might actually make you feel worse by further dehydrating you and irritating your stomach.
Practical Steps to Feeling Human Again
If you need to be functional within the next two hours, follow this protocol. It isn't magic, but it's the most effective way to mitigate the damage based on current medical understanding.
- Hydrate with a 2:1 ratio. Drink two glasses of water for every one glass of electrolyte solution. Too much electrolyte powder without enough water can actually pull more moisture out of your tissues.
- Eat "The BRAT Diet." Bananas, Rice, Applesauce, Toast. These are easy on the stomach and provide the glucose your brain is screaming for.
- Control the light. Photophobia (light sensitivity) is a symptom of the meninges in your brain being irritated. Wear sunglasses, even indoors. It sounds ridiculous, but it reduces the sensory load on your brain.
- Fresh Air. It sounds like old-wives' advice, but light movement and oxygen can help move your metabolic rate just enough to make a slight difference in how you perceive the pain.
Next time, try to drink a glass of water between every cocktail. It’s the only proven way to prevent the state you’re in right now. For today, focus on keeping your blood sugar stable and your inflammation down. Your liver is doing its best; just give it some space and don't add any more toxins to the mix while it works through the backlog.
