acne
"I originally started taking Yaz for birth control, but instantly noticed that my face cleared up.  Yaz works wonders for acne, and I highly recommend it.  However, it made my emotions go crazy.  I became very anxious.  I was on it for a year and then decided to get off of it.  My anxiety decreased but acne slowly came back.  Now I am going to try it again for acne and hope that I can cope with the anxiety from it.  I'm out of school now so I'm hoping this makes it easier to cope with the side effects.  Also, I did not gain any weight, and my boobs grew a full size.  It's a myth that birth control causes weight gain, it only causes increase in appetite or causes you to crave a certain food (i.e. sugar) which in turn causes you to gain weight"
