Yes, I've been on Topamax for several years. It works quite well as a mood stabilizer and doesn't cause the weight gain that many other similar drugs do.

Having an ed, I couldn't cope with being on a medication that caused a weight gain--this is one reason my doctor prescribed the Topamax. It really shouldn't be too much of a problem for you. It doesn't so much kill your appetite...it just doesn't make you gain.
