i took xenical for about 2 months last year. I gained a lot of weight after my hysterectomy 2 years ago, and I would complain to my doctor that no amount of "dieting" and excercising would get rid of it. He put me on the xenical and I was horrified with the side effects. I got the first prescription filled took that got second month filled and only took it because I paid so much for it. In the end, I was only lighter in the wallet from xenical.
