I have been taking topomax 100mg twice a day for one year. I began taking it for seizures and headaches. I weaned myself off of it in December feeling that it was unnecessary being that I've always been on lamictal as a monotherapy treatment for my seizures and that the dizziness, memory problems and tingly feelings were not worth it. Now the ten pounds that I originally lost and kept off for all this time has came back on and all the while I have been exercising 1 1/2hrs a day (which is new to me) and it isn't helping. I am back at my normal weight of 123 whereas I was happy to be 113 while on the drug. I am going to begin taking it again to see what happens... I don't experience the symptoms I spoke of before-unless I take too much because my memory is bad.
