I went on aviane back in December and i mainly just got mood swings and depression, but i wanted to go on it to clear up the pimples i was getting. I went off it a month or two later because of rapid weight gain that i noticed and now in may ive been on it for about a week and im already experiencing horrible mood swings, horrible cysts of pimples that happen to be very painful, and im just never happy. I also experience really bad stomach pains and I am not sure if this is all because of the pill? I don't know if i should keep through with the pack hoping that it will get better? I have prom in a few weeks and i don't want my face to look horrible. I was thinking about going on YAZ because of the commercials saying that it clears acne, controls mood swings, etc....what do you think?
