I like it too. Sometimes I feel that it isn't working but my psych has said that he sees a big difference in my mood since I started it. I have been on it twice now and both times it has reduced my appetite (which is not a bad thing) but now it is just keep the potential weight gain from other meds at bay.
I was a little nervous to try it originally because I didn't have a good experience with Lamictal personally but with Topamax it was completely different......well worth the try in my opinion
