Sports Drinks
"Even though the diuretic effect of alcohol may cause the body to lose some electrolytes, it's not so much that you need to replace them right away," says Samir Zakhari, Ph.D., director of the Division of Metabolism and Health Effects at the National Institute on Alcohol Abuse and Alcoholism. And research has shown Gatorade is no better for a hangover than water from your tap, so save your money.
Coffee
Lots of people—hungover or not—use a cup of joe to wake up and feel alert at work. But a trip to Starbucks won't give you lasting benefits, and caffeine can both treat and cause headaches and migraines, so this one is a personal preference. If you do down a cup, be sure to drink water, too, since studies suggest caffeine causes dehydration.
More Alcohol ("Hair of the Dog")
"Bad idea," Dr. Hall-Flavin says. "It will provide a numbing effect, but all you're doing is prolonging the inevitable, and it will likely make your headache worse." Another reason to avoid cracking open a cold one: Experts agree that if you use this "cure," the risk of abuse increases and could lead to alcohol dependency.
Toast or Crackers
Remember when your mom gave you toast as a kid when you couldn't keep anything down? This is good advice for adults who've spent the night hugging the porcelain throne, too. While no food can halt the roller coaster in your stomach, carbs can help bring your blood sugar levels back up the morning after, Dr. Hall-Flavin says. Normally when blood sugar levels dip, your liver reacts by producing more glucose from stored carbs. But if you've been drinking too much, your liver is busy metabolizing the alcohol and can't handle the extra work, so your blood sugar levels stay down, and you can feel irritable and tired.
Greasy Food
What you eat after drinking doesn't matter—it's what you eat before all those Jagerbombs that can help lessen the pain the next day. Food helps slow the absorption of alcohol, and the longer it takes the alcohol to reach your blood stream, the longer it is until you become intoxicated.
Pain Medication
Ease a pounding head with a pill (or two, depending on the recommended dosage), but stick to nonsteroidal anti-inflammatory drugs (or NSAIDs, such as aspirin, ibuprofen, and naproxen).
Vitamins
If you normally take a multi, go ahead, but no studies have found that any particular vitamins do anything for a hangover. And one night of intoxication isn't enough to throw off the levels of nutrients in your body to the point where you need to worry.
Exercise
One drink—a 12-ounce beer, 5 ounces of wine, or 1.5 ounces of hard liquor—is metabolized by your body in about an hour, so the whole "sweat it out" theory is myth. At the same time, the endorphin release could boost your mood. And burning off a few calories may ease your guilt about how much you drank. Just be sure you keep your water bottle handy so you don't become even more dehydrated.
The Best Cure: Prevention
You're a grown man / woman, you know to drink responsibly. But just in case you forgot: Limit your drinks to about one every hour. Your body metabolizes each beer (or wine or shot) in about 60 to 75 minutes, Dr. Hall-Flavin says. Drink faster, and your blood alcohol level rises faster. Eat before you drink and follow Dr. Hall-Flavin's "I'll have a beer and a glass of water" rule when ordering—and drink the water, don't let it just sit on the table.
