I had been once every two years since I was 18 until 24. Some kind of pattern I guess & a lot of misdiagnosis. In some ways it helped but everytime they would add an AP and I would gain weight, I gained over 100 lbs over the years. Now being out for 5 years and off APs for a few years I have lost 65 lbs and am very happy. It is my #1 goal to stay out of there and off APs
