I hate Yaz period! It has made me a crazy, inconsistent, bad mood having, cramps like you wouldn't believe mad woman! I was told it would help with my bloating, false, cramping, false, less days, false! I had been on a previous "Birth control" and even that didn't make me feel any of this. Had I known, I would not have switched to Yaz. Yes true everyone reacts to them differently but trust me you want less of "our kind" around. You feel completely out of control, irritated, like you just wanna choke anyone who asks you a stupid question. I am definitely switching...I cannot take this anymore...at 34, I have enough to deal with as it is!
