Let me just say THANK GOD for this website...i began taking yaz last may because i saw so many commercials for it and thought it would be great... all summer long i LOVED it and raved about it to anyone who would listen, probably because of the rapid breast growth it caused ( i went from a small b to a double d in a period of six months), but ive been feeling extremely melancholy and moody as of late, and i have ZERO patience; ill snap at the smallest thing. but what inspired me to finally get off of yaz is the weight gain; i used to have a wonderfully toned body, very nice abs and muscular slender legs; since taking yaz, i have gained 17 POUNDS and working out incessantly and watching my diet is doing absolutely NOTHING to help this weight gain...it didn't cause acne, but ive never had acne so im not sure if that side effect really applies to me...but im constantly tired, bitchy, and craving junk food, even when im not hungry. all i want to do is nap all day long and im just extremely depressed all the time. im throwing my pack out as we speak and i suggest anyone who is having similar side effects do the same because they always get worse.
