Avoid Coffee
Avoid CoffeeWe're coffee addicts, but when we're hungover, the worst thing we can do is grab a 16-ounce cup of coffee. Since the drink is a diuretic, it dehydrates the body even further. Caffeine is also a vasoconstrictor,so it causes blood cells to swell, which means your headache will only get worse with every cup. Stick to herbal tea, juice, or water instead. [Photo via]
