I have been on yaz for a month now. I was taking apri before and was switched when I found out that I possibly had a cyst that has burst. I was in a lot of pain, but the gyno said that she thought taking birth control would help but didn't like what I was taking. So now for the past few weeks, I can't sleep, dizziness, headaches, crying hysterically for no reason, lack of sex drive, extreme fatigue, irritability, moody, feeling hopeless, feeling out of it, can't remember things very well, can't concentrate, and my eyes are sometimes blurry. I am hoping this is just an adjustment period. But after reading other peoples side effects, I am starting to wonder. I will wait another month or two, but if it doesn't stop, I am going back to apri.
