I'm 50 and was having a hard time with perimenopause and really heavy periods. This was the end of my 2nd month on Yaz. I had lots of headaches and tracer like lights (floaters) but everything else was okay, maybe a little depressed. But suddenly this week (with 5 pills left before the white ones) I started having uncontrollable panic attacks. I went to the dr. and came home with Valium (talked myself out of going on Zoloft). Then things got so bad on Saturday I went to the dr. and got some Zoloft. While at the pharmacy I asked about anxiety and panic attacks having something to do with Yaz. She said yes. I came home and found this site. Zoloft is still in the bottle. I threw the rest of the Yaz away. I like the weight loss, shorter period, less PMS, but I can't function having panic attacks. Guess I'll just go cold turkey on perimenopause - it can't last that much longer (yeah, right! ;-))
