I was prescribed YAZ in Nov 2006. Initially it was not that bad.....here recently I have been experiencing horrible side effects. I was having bad migranes, i was getting sick all the time, I had the shakes, anxiety attacks, insomnia, etc...I have decided to get off of the YAZ. It made me feel horrible. I still have some side effects....thankfully I have no more anxiety attacks....I do still have the shakes and headaches though, sometimes I still feel sick. I hate what this birth control did to me. I don't even want to get on another one because I am scared it will make me sick like YAZ did
