Thank you Renee for your reply. In my case though my appetite was not increased while on the meds. In fact, it decreased so much that I went into starvation mode. I continued to gain weight even without eating. My doctor wanted to put me on an appetite suppressant, but I became outraged when he suggested that even after I told him I was barely eating already.
I have been off the meds for 3 months now and have been involved in a monitored fitness program and have been on a 1,200 cal. a day diet. Over the last 3 months I have not lost ANY of the weight, not even one single pound. I do weight training twice a week, cardio twice a week, and mountain bike ride each weekend. That's exercise 6 days a week along with the diet and there has been no change in the weight.
I post on any board I think I can find answers to this problem and I have found that there are thousands of people who are also suffering from this. some have gained up to 100lb in less than a year on these meds. Each one says they were not told of the deforming weight gain ahead of time.
