The morning after heavy drinking, your body is dealing with dehydration, disrupted sleep, low blood sugar, and the lingering toxic byproducts of alcohol metabolism. Most hangovers resolve on their own within 24 hours, but what you do in those hours can make a real difference in how quickly you feel normal again. Here’s a practical plan for getting through the day.
Why You Feel This Bad
When your liver breaks down alcohol, it first converts it into a toxic compound called acetaldehyde, then into harmless acetate. Acetaldehyde is the real villain: it causes rapid pulse, sweating, nausea, and flushing. In most people, the liver clears it efficiently, but after heavy drinking, the sheer volume overwhelms the system. Even after your blood alcohol level hits zero, the damage from acetaldehyde lingers into the next day.
On top of that, alcohol blocks your liver from producing new glucose, which is why your blood sugar drops. It also suppresses REM sleep, the deep restorative phase your brain needs for emotional regulation, memory, and feeling rested. You may have fallen asleep quickly, but the second half of your night was likely fragmented, with more wake-ups and poorer sleep quality overall. That explains the brain fog and exhaustion even if you were technically in bed for eight hours.
Hydrate, but Don’t Overdo It
Alcohol is a diuretic, so you lost more fluid overnight than usual. Water is the obvious first step, but drinking a huge amount at once can make nausea worse. Sip steadily throughout the morning instead. Adding an electrolyte source helps, whether that’s a sports drink, coconut water, or a pinch of salt in your water. Potassium matters too: bananas, avocado, or broth-based soups are easy options if solid food feels like a stretch.
What to Eat (and When)
Your blood sugar is likely low, and your instinct will be to reach for something sweet. Resist the urge to load up on sugary foods or juice. After alcohol disrupts your blood sugar regulation, simple carbohydrates cause a sharp spike followed by another crash, leaving you feeling worse an hour later. Instead, pair complex carbohydrates with protein and fat: toast with eggs, oatmeal with nuts, or a rice bowl with some kind of protein.
Eggs are a particularly good choice. They’re rich in the amino acid L-cysteine, which helps your body break down acetaldehyde. A 2020 study found that L-cysteine supplementation reduced hangover nausea, headache, and anxiety. You’d need a much higher dose than what’s in a plate of scrambled eggs to match the study’s 1,200 mg, but combined with other recovery strategies, it contributes. Eggs also contain B vitamins that alcohol depletes.
Foods high in zinc and a B vitamin called nicotinic acid (found in chicken, meat, fish, legumes, and whole grains) have been linked to less severe hangovers. One study found that higher dietary zinc intake was strongly associated with less vomiting, and both zinc and nicotinic acid were significantly correlated with lower overall hangover severity. A meal built around whole grains and lean protein checks these boxes naturally.
If nausea makes eating feel impossible, start with something bland and small: plain crackers, a slice of dry toast, or a few spoonfuls of broth. Ginger tea or ginger chews can help settle your stomach enough to eat a real meal later.
Go Back to Sleep If You Can
Because alcohol suppresses REM sleep in the first half of the night and causes fragmented sleep in the second half, your brain didn’t get the restoration it needed. A nap is one of the most effective things you can do. Even 20 to 90 minutes of sleep, now that the alcohol is out of your system, will be higher quality than what you got overnight. If you can’t nap, at least rest. Pushing through a packed schedule will extend how long you feel rough.
Skip the Acetaminophen
Reaching for a painkiller is tempting, but choose carefully. Acetaminophen (Tylenol) is processed by the same liver pathways that just spent hours dealing with alcohol. Chronic alcohol use and fasting, both common in a hangover scenario, reduce your liver’s protective reserves and increase the risk of liver damage from acetaminophen. This isn’t a theoretical risk: it’s a well-documented pattern in clinical literature, and it can occur even at standard doses in people who drink regularly.
An anti-inflammatory like ibuprofen is generally a safer pick for hangover headaches, though it can irritate an already-sensitive stomach. Take it with food, and keep the dose modest. If your stomach is too upset for either option, a cold compress on your forehead and temples can take the edge off a headache without any medication.
Move Gently, Skip the Hard Workout
Light movement can help. A short walk, some stretching, or easy yoga gets your circulation going without taxing a body that’s already dehydrated and low on fuel. There’s some evidence that mild exercise may support your liver in clearing alcohol metabolites slightly faster.
An intense workout, however, is a bad idea. You’re dehydrated, your coordination is off, your blood sugar is unstable, and your heart rate is already elevated from the acetaldehyde exposure. Research on alcohol and exercise shows that alcohol increases injury rates during physical activity and impairs performance capacity. Save the gym for tomorrow.
What Won’t Help
“Hair of the dog,” or drinking more alcohol the next morning, temporarily masks symptoms by re-sedating your nervous system, but it just delays the hangover and adds more toxins for your liver to process. It also reinforces a cycle that can lead to dependence over time. Coffee is fine in moderation if you’re a regular coffee drinker, but it’s a diuretic, so match every cup with extra water.
Greasy fast food is another common instinct. While fat does slow absorption of things in your stomach, the alcohol is already absorbed and metabolized. A heavy, greasy meal is more likely to worsen nausea than cure it. Stick to balanced, nutrient-dense food instead.
A Realistic Timeline
Hangover symptoms peak in the morning once your blood alcohol level drops to zero, and most people start feeling noticeably better by mid-afternoon. The full cycle typically resolves within 24 hours for a standard night of heavy drinking, though very heavy sessions can stretch discomfort into the following day. If you hydrate, eat well, rest, and avoid making things worse with the wrong painkiller or another drink, you’ll shave hours off that timeline. By evening, most people feel functional again, if a little tired.
