You can’t speed up how fast your body clears alcohol. Your liver processes roughly one standard drink per hour, and nothing changes that rate. What you can do is manage the symptoms, replace what your body lost, and avoid making things worse while you wait. Here’s what actually helps and what doesn’t.
Why You Feel This Way
Hangover symptoms peak right around the time your blood alcohol level drops back to zero. That timing isn’t a coincidence. As your liver breaks down alcohol, it creates a toxic byproduct called acetaldehyde, which triggers inflammation in your brain, gut, liver, and other organs. Your body also has to rehydrate, heal irritated tissue, and restore normal immune and brain function. The whole process can take 24 hours or longer depending on how much you drank.
Alcohol suppresses a hormone that tells your kidneys to hold onto water. Without that signal, your kidneys flush fluid at a much faster rate than normal, pulling water from your blood and sending it straight to your bladder. That’s why you urinate so frequently while drinking, and why you wake up dehydrated, headachy, and foggy the next morning. The fluid loss also drains electrolytes your muscles, nerves, and brain need to function properly.
Rehydrate With More Than Water
Water is the obvious starting point, but it’s not the whole picture. You lost electrolytes overnight, so drinks that replace sodium, potassium, and other minerals will help you feel better faster. Sports drinks, electrolyte packets, or even broth all work. Sip steadily rather than chugging. If your stomach is sensitive, small frequent sips are easier to keep down than a full glass at once.
Coconut water is another solid option since it’s naturally rich in potassium and easy on the stomach. The goal is consistent intake over the course of the morning, not one heroic glass of water before bed (though that helps too, if you remember).
Eat Something, Even If You Don’t Want To
Alcohol disrupts your blood sugar levels, which contributes to the shakiness, weakness, and brain fog you feel the next day. Eating carbohydrate-rich foods helps stabilize your blood sugar and settle your stomach. The classic BRAT approach (bananas, rice, applesauce, toast) works well because these foods are bland enough to tolerate when you’re nauseous and provide the quick energy your body needs.
Bananas are especially useful because they’re high in potassium, one of the key electrolytes you lost. Eggs are another good choice if your stomach can handle them, since they provide protein and amino acids that support your liver’s recovery process. Avoid greasy, heavy meals. They won’t “soak up” alcohol that’s already been absorbed, and they can make nausea worse.
Choose the Right Pain Reliever
If your head is pounding, reach for ibuprofen (Advil) or naproxen (Aleve). Both are anti-inflammatory, which addresses one of the core mechanisms behind hangover headaches.
Do not take acetaminophen (Tylenol, Excedrin) while your body is still processing alcohol. The combination puts serious stress on your liver, which is already working overtime to clear alcohol’s toxic byproducts. The FDA specifically warns people who drink three or more alcoholic beverages a day to talk to a doctor before using acetaminophen at all. After a heavy night of drinking, this risk is real. Stick with ibuprofen or naproxen, and take them with food to protect your stomach lining, which alcohol has already irritated.
Coffee Won’t Sober You Up
Caffeine is one of the most persistent hangover myths. It does not speed up alcohol metabolism. Studies co-administering caffeine with alcohol found no significant effect on blood alcohol concentration. Caffeine doesn’t improve motor coordination or visual reaction time impaired by drinking, either. What it does is mask the feeling of intoxication, making you feel more alert while your body remains just as impaired underneath.
That said, if you’re a regular coffee drinker, skipping your morning cup will add a caffeine withdrawal headache on top of your hangover. A small amount of coffee is fine for preventing that. Just don’t count on it to accelerate your recovery, and drink extra water alongside it since caffeine is also a mild diuretic.
Skip the IV Drip
Hangover IV clinics have become trendy, offering bags of fluids, electrolytes, vitamins, and sometimes anti-nausea medication delivered through a needle in your arm. The appeal is obvious, but the medical consensus is underwhelming. Doctors at the University of Rochester have noted that IV fluids aren’t recommended unless a patient genuinely cannot keep water down. For most people with a standard hangover, oral rehydration works just as well. IV fluids also carry small risks: they require bloodwork to be administered safely, and for some people they can actually cause complications. Save your money and drink fluids the regular way.
What You Drank Matters
Not all hangovers are created equal. Darker spirits like bourbon, brandy, and whiskey contain far more congeners, chemical byproducts of fermentation that make hangovers worse. Bourbon contains roughly 37 times more congeners than vodka. Red wine is also high in congeners, particularly methanol, whose breakdown products (formaldehyde and formic acid) are highly toxic in small amounts. Research has consistently shown that hangover severity is proportional to the congener content of what you drank. If you had a rough night on whiskey or red wine, that’s part of why you’re feeling it more than usual.
Beer and vodka sit at the low end of the congener spectrum, which is one reason they tend to produce milder hangovers at equivalent alcohol amounts. This won’t help you right now, but it’s worth remembering next time.
The Realistic Recovery Timeline
Your body needs to finish clearing acetaldehyde, rehydrate, repair irritated gut lining, and reset its immune response. There’s no shortcut through that process. For a moderate hangover after four or five drinks, most people feel significantly better within 12 hours. A heavier session can leave symptoms lingering for a full 24 hours or more.
The most effective recovery plan is boring but reliable: drink fluids with electrolytes, eat bland carbs, take ibuprofen if you need it, and rest. Sleep is genuinely restorative here because alcohol disrupts your sleep architecture, and your brain needs real, uninterrupted rest to recover. If you can nap, do it.
Supplements: Promising but Unproven
Dihydromyricetin (DHM), a compound extracted from the Japanese raisin tree, has generated real scientific interest. A USC study found that in mice, DHM boosted the liver enzymes responsible for breaking down alcohol, reduced fat buildup in liver tissue, and lowered inflammation. The mechanism is compelling: it appears to activate energy-regulating pathways that speed the metabolism of alcohol and its byproducts.
The catch is that this research has been conducted in animals, not humans. No large-scale human clinical trials have established effective dosages or confirmed these benefits translate to people. DHM supplements are widely available, and many people swear by them, but the evidence isn’t strong enough yet to call them a proven remedy. B vitamins and zinc supplements have also shown some association with milder hangovers in small studies, but again, the data is preliminary. These supplements are generally safe to try, but don’t expect miracles.
