I have been taking Yaz for almost two weeks and it has been awful. I ran out of Yasmin and my doctor's office gave me a sample pack of Yaz - I was reluctant to try something new but went ahead with it because I read that it was similar to Yasmine. Not true! I started getting headaches every day and after only a couple days of taking the pill I got really sad. I didn't feel like my normal happy self at all. Every day it got a little worse and I got a little sadder and more depressed. I was also getting mad at things. Mad at work, mad at people I just had this overall feeling of being unhappy. I am normally a cheerful "look on the bright side" kind of girl. I have also been uncontrollably hungry. I literally could not stop eating on Friday. I had to leave my house to stop. On Saturday I started crying for no reason. Last night I snapped out at my boyfriend for no reason and he thought I was crazy. I did some research and found out that many other women were experiencing some of these symptoms. I am not taking another one of those pills from this moment on. If you haven't taken this pill before think twice.... it was an emotional rollercoaster for me.
