I started taking Yaz because i have PMDD.. every month I was very moody for about 10 days before my period and it was hell to be around me...i would scream at everyone for no reason,have a very bad temper, and i was ALWAYS angry!!! i decided to take Yaz because i was sick of the mood swings. After two weeks of taking Yaz I have been MORE moody than i EVER have been, which in my case is a very bad thing and i thought was impossible..i have been going absolutely CRAZY! also i have been neasuated every day(throwing up), i have been eating way more at weird hours, i cant fall asleep, very depressed about life, my legs and arms have been getting numb.. i normally go to the gym everyday and have only gone twice in the past two weeks, all i do now is sit on the couch and watch tv...I HATE THIS PILL...I SUGGEST YOU DO NOT TAKE IT! read all these reviews no one has had good results with this. i was going to continue taking it to see if these symptoms would go away, but after reading all these posts i am stopping today! thank you!
