I had been on Yaz for about 1 1/2 years with little to no problems until the last couple of months I began to get severely depressed and experienced suicidal thoughts about midway through the pack. The rest of the month I felt like I was in an emotional and mental fog. My husband recognized a difference in my behavior after a couple of months of starting yaz. I finally broke down and called my doctor. She decided to put me on Yasmin... now that I have read through some of the thousands of side effects of Yasmin on this website, I'm not so sure that anything is going to get any better....
