I am so thankful I found this website. I started taking Yaz in May of '08. By the middle of June, I thought I was going crazy! Tightness in my chest, uncontrollable crying and thoughts. It ruined my whole summer with my girls, I became withdrawn and depressed. By the time I realized that Yaz was the only thing that I had done differently, I was having major heart palpitations, talk about scary. Here it is 6 months later, and I'm wearing a heart monitor for 21 days to capture these heart palpitations, that I am still having. I have been going around telling everyone that will listen to me, DO NOT TAKE YAZ!!!!!!!!!!!!!!!!!!!!!!!!
