Yaz helped me with my PMDD, but I ended up with a pulmonary embolism and now I can't take birth control or hormones of any kind, ever. My PMDD is back in full swing and I am so frustrated! If you decide to try Yasmin or Yaz as a treatment you should know that blood clots and pulmonary embolisms are not uncommon side effects. I could have died if my doctor had not know suspected right away what was going on and got me to the hospital. I'd rather be a wacko and alive than levelheaded and dead.
