I was on Topamax for about a year. I lost 50 Ibs because, I did not have an appetite. I decided to go off of it. Then I started to gain weight back and wanted to go back on it but, I had terrible itching and every time I got sweaty or in the sun I would start to itch. Now it has been about 9 months that I have been off of it. I have problems with migraines and I also would like to try it to help lose weight but, I am trying to weigh the risks because I don't want that itching problem to start back. Oh yeah...I did not have many problems with memory loss or anything. I liked how I could think everything out more slowly. Basically...I felt like I could concentrate better on stuff and not have racing thoughts. So that was a plus for me. Also had tingling in my toes for about the first 5 or 6 months on it.
