Transcript: Okay, you're never drinking again. But how can you fix that hellish hangover? First things first: You've got a hangover because your body has lost nutrients and electrolytes . To counteract the nauseous, headachy effects, you need to replace those lost nutrients. Start by re-hydrating. Guzzle sports drinks, which contain electrolytes, fruit juice, and, of course, lots of water. You'll want to steer clear of coffee, though, as it'll dehydrate you further. Now eat something light and nutritious, like a banana or yogurt. After you've had something to eat and something (non-alcoholic) to drink, get some gentle exercise. You may not feel like moving, but a brisk walk can be just the healing help you need. That's because exercise increases blood flow and helps rid you of toxins that are left from your body's attempt to metabolize that alcohol. These tips are less elaborate than your best friend's hangover cure (pickle juice and honey, yuck!), but they'll actually work-and that's worth a lot!
