I began taking Topamax for partial seizures in January, 2005. I have since lost 25 pounds (I am 5' 2" and am down to 102 lbs.). I just really have no appetite most of the time. I am wondering if others have lost weight like this on Topamax and if so, has the weight stayed off, or did you gain it back? I am 42 years old and was diagnosed with TLE in March of 2004. I took Keppra for awhile, but had breakthrough seizures and when my dosage was increased, my hair started falling out. So my neurologist switched me to Trileptal. I had terrible headaches on this med, so started the Topamax this past January. It seems to be working, though I'm a little concerned about the weight loss.
