birth control
"This pill worked great for clearing up my acne on my face and back. It took a few months but once it worked it really did help for that. It also worked really well at preventing pregnancy which it should. However, this pill made me gain like 10 pounds... I didn't really notice when I was on it, but once I went off of it I lost a substantial  amount of weight...It also made me act crazy. I was constantly yelling at people and losing my temper. It didn't have my friend gain weight when she took it so I guess side effects vary from person to person... I don't think I'd recommend it though."
