Topiramate and Weight Loss

I had this discussion with my doctor and he was not too concerned, as I have always been a little overweight; but I am a little worried because of the quickness of my weight loss since I have been on Topiramate. I was 165 pounds when I started taking this drug. Now I am sitting at just below 140. I started the medication less than two months ago, and I am on a dose of 100 mg. twice a day. I have fought with my weight for most of my life and have never had this type of weight loss in this time frame. Usually for me to lose this amount of weight, it takes me at least five months of hard dieting and exercise because of my bad gene-pool. My diet has not changed (aside from me eliminating more meat and adding more fruits and veggies, and incorporating more juice), and I am not taking any other medications that might have caused this weight loss. Is this weight loss going to continue or is this just a temporary side effect until I fully adjust to the medication? Should I be worried? How much weight loss is too much with this drug? Any advice is appreciated and happy new year :-) Regards, Kat
