I initially lost 25 pounds when I first began taking the Topamax. Then the pdoc became concerned due to the ED that I had, and monitered my eating and so forth, and made me regain 10-15 pounds. After that, I was put on Abilify, of which is a weight neutral medication. Of course, I have bad luck, and was one of the few people on the planet that gained weight on the Abilify. ugh! I now have regained the weight plus some.... oh, and add menopause into the mix and WOOOLAAHHH! Metabolism mess!!
Hang in there. My heart goes out to you. I totally understand your frustration.
