"i have been using yaz for almost 3 years now. i have no mood swings and my acne cleared completely, i get one or 2 zits before i get my regular period once a month. i gained a few pounds but it can be fixed, i am 20 years old and i have no mood swings, sex drive is the same and i love this pill. i used to be on the nuvaring for a year but it made me moody. so yaz is the best thing ever invented to reduce human overpopulation!"
