The best things to take after drinking are water, electrolytes, foods that stabilize blood sugar, and specific nutrients that help your body clear alcohol’s toxic byproducts. What you avoid matters just as much: acetaminophen (Tylenol) combined with alcohol can cause serious liver damage, and “hair of the dog” only delays the inevitable.
Here’s what actually works, and why.
Water and Electrolytes Come First
Alcohol is a diuretic, meaning it pulls water out of your body faster than you’re replacing it. That fluid loss drags essential minerals like sodium, potassium, and magnesium along with it. Much of what you feel the morning after, including the headache, fatigue, and dizziness, traces back to this dehydration and mineral imbalance.
Plain water helps, but it doesn’t replace what you lost. A drink with electrolytes (coconut water, an oral rehydration solution, or even a pinch of salt in water with a squeeze of citrus) restores balance faster. Aim to drink at least a full glass of water before bed and continue hydrating steadily the next morning. Sports drinks work in a pinch, though many are loaded with sugar that can make nausea worse.
Food That Stabilizes Blood Sugar
Alcohol disrupts your blood sugar in a way most people don’t expect. It blocks your liver’s ability to produce new glucose, a process called gluconeogenesis. At the same time, it can trigger your pancreas to release too much insulin, causing blood sugar to drop well below normal. The result is that shaky, weak, brain-foggy feeling that often accompanies a hangover.
Your body responds to this crash by pumping out adrenaline to force stored sugar back into the bloodstream, which is partly why you might wake up anxious or jittery after a night of drinking. The fix is eating, but what you eat matters. Simple carbohydrates like white bread, sugary cereal, or pastries spike your blood sugar fast and then drop it again, restarting the cycle.
Better choices include whole grains, eggs, avocado, or oatmeal with nuts. The combination of complex carbohydrates, protein, and healthy fat slows absorption and keeps blood sugar steady. Eating before bed helps too, and eating again at regular intervals the next day prevents further dips.
B Vitamins, Especially Thiamine
Alcohol depletes B vitamins rapidly, particularly thiamine (B1), folate (B9), B6, B12, and riboflavin. These vitamins are water-soluble, meaning your body doesn’t store large reserves of them, and alcohol accelerates their loss through increased urination and impaired absorption in the gut.
Thiamine is the most critical. It plays a central role in energy metabolism and nerve function, and even moderate drinking can lower your levels significantly. For people who drink occasionally, a B-complex supplement taken after drinking and again the next morning can help replenish what was lost. A daily multivitamin with minerals covers the broader spectrum of micronutrients, including folate, which supports red blood cell production and is commonly low in regular drinkers.
You don’t need megadoses. A standard B-complex or multivitamin provides enough for recovery from an occasional night out. The clinical protocols involving high-dose IV thiamine are designed for chronic heavy drinkers at risk of serious neurological complications, not for someone recovering from a weekend dinner party.
Glutathione and Its Building Blocks
When your liver processes alcohol, it first converts it to acetaldehyde, a toxic compound that’s 10 to 30 times more harmful than alcohol itself. Acetaldehyde is responsible for many hangover symptoms: the flushing, nausea, headache, and racing heart. Your body neutralizes it using an enzyme, but also relies heavily on glutathione, your cells’ primary antioxidant and detoxifier.
A randomized, double-blind clinical trial found that people who took a glutathione supplement before drinking had significantly lower blood levels of acetaldehyde at nearly every time point measured, from 15 minutes to 15 hours after drinking. The dose used was modest, just 50 mg of glutathione from a yeast-based extract. The supplement essentially gave the body extra raw material to scavenge acetaldehyde before it could do as much damage.
If you can’t find a glutathione supplement, its building blocks work too. Glutathione is made from three amino acids: cysteine, glycine, and glutamate. N-acetyl cysteine (NAC) is the most popular precursor supplement because cysteine is the rate-limiting ingredient your body needs most. Foods rich in cysteine include eggs, yogurt, garlic, and poultry.
Ginger for Nausea
Ginger has a long track record for calming nausea from motion sickness, chemotherapy, and pregnancy. Its compounds speed up stomach emptying and act on serotonin receptors in the gut that trigger the urge to vomit. For post-drinking nausea, ginger tea, ginger chews, or even flat ginger ale (with real ginger) can settle your stomach when nothing else sounds appealing. It’s gentle enough to take on an empty stomach and pairs well with the rehydration you should already be doing.
Why Acetaminophen Is Risky After Drinking
Reaching for Tylenol to treat a hangover headache is one of the most common and most dangerous mistakes. Alcohol changes the way your liver processes acetaminophen, causing it to produce more of a toxic byproduct that can kill liver cells. The American College of Gastroenterology states plainly that people who drink regularly should not take acetaminophen, and that even occasional drinkers should never take the maximum recommended dose after alcohol.
Ibuprofen (Advil, Motrin) or naproxen (Aleve) are safer alternatives for headache and body aches, though they carry their own risk of irritating an already inflamed stomach lining. Taking them with food reduces that risk. If your stomach is too upset for anything, a cold compress on your forehead and continued hydration often do more than a pill anyway.
Why “Hair of the Dog” Doesn’t Work
The idea that another drink cures a hangover has been around for centuries. The logic seems sound on the surface: if you feel terrible once the alcohol leaves your system, putting more alcohol back in should fix it. And it does, temporarily, in the same way that any drug relieves its own withdrawal symptoms.
But a hangover is not the same as alcohol withdrawal. Withdrawal happens to people with physical dependence after chronic heavy drinking. A hangover happens to anyone after a single session. Drinking more the next morning just delays your body’s recovery process while adding more acetaldehyde, more dehydration, and more nutrient depletion to the pile. You’ll feel the same or worse a few hours later, now with an extra drink’s worth of toxins to process.
A Practical Recovery Timeline
The order you do things matters almost as much as what you take. Before bed on the night you’ve been drinking, have a large glass of water with electrolytes, eat something with protein and complex carbs if you can manage it, and take a B-complex vitamin.
When you wake up, drink more water or an electrolyte solution before reaching for coffee (caffeine is a diuretic and can worsen dehydration if you haven’t rehydrated first). Eat a balanced meal even if you don’t feel hungry. Eggs are an especially good choice because they’re rich in cysteine, the amino acid your body uses to rebuild glutathione and clear acetaldehyde. If nausea is keeping you from eating, start with ginger tea and small sips of broth until your stomach settles.
Most hangover symptoms peak around 12 to 14 hours after your blood alcohol level hits zero and resolve within 24 hours. Supporting your body with fluids, electrolytes, the right foods, and targeted nutrients won’t eliminate a hangover entirely, but it shortens the window and takes the edge off the worst of it.
