Rehydrate. Alcohol is a diuretic, meaning that once you “break the seal” you’re pretty much expelling all of your body’s liquids at regular intervals. To take the edge off, down a full glass of mineral water as soon as you get up. If you can manage another glass every half hour for a couple of hours then so much the better, but at the very least attempt to rehydrate every hour on the hour with either mineral water, fruit juices, or herbal teas. Don’t fall for the old wives’ tales that coffee or a little hair of the dog is best, as both will further dehydrate you and make you feel even worse.
Find some fruit. Vitamin C helps increase the rate of alcohol breakdown in your system, so if at all possible, try to consume oranges, strawberries, or tomatoes (juice form works as well). If you’re a veggie eater, red peppers, broccoli, or a potato are good options.
Chow down. Food really can help to soak up some of the alcohol in your stomach, which will slow the rate at which it enters the blood. Try to eat a meal balanced in fat, protein, and carbs, but if you really want the cheeseburger and fries, by all means, go for it.
Chill out. Literally. If you’ve got a pounding head or puffy eyes, chill out with an ice pack (frozen veggies will do in a pinch). Wrap your preferred compress in a towel to avoid hurting your skin and apply it for 10 minutes on, 10 minutes off as needed. Then stretch out in front of cheesy TV or, better yet, go back to bed. Remember, the only truly proven cure for a hangover is time, and if you can spend some of it unconscious, all the better.
