I am so glad to have found this website. Similarly to others, I thought that I was going crazy. I have been taking Yaz for 3 months, but I am stopping today! I have had many side effects including MOOD SWINGS, anxiety, snapping at people for no reason, spotting, decrease in sex drive, difficulty staying asleep, tightness/tingling in upper left arm, warmth in groin area, breast tenderness and nausea. If this pill causes such severe side effects for so many people, why doesn't the FDA remove it from the market? Argggggg
