Sorry if this question has been answered before. I'm about to start taking Topamax for binge eating disorder, and I've heard it can cause weight loss, which would be welcome in my case. What I'm worried about is losing a ton of weight and then gaining it all back as soon as I go off the medication (which I probably will do eventually). Have any of you lost weight on Topamax and successfully kept it off after stopping the medication? Or does everyone gain back whatever they lost and then some?
