I used to sweat terribly, but not as bad as some people i know who used to sweat through their makeup. I got in the habit a few years ago of drinking a litre of water a day, and that really helped. I swear by it, it makes you feel so much healthier and water truly does the body good. My friend hates water so she mixes some lemon with it, just for some taste, and drinks a litre like I do. Every day i put a litre of water in the fridge and make sure i drink it.
