To anyone thinking of trying topamax because it did remove the racing thoughts, voices etc I have to let you know my side effects besides removing my obsessive racing thoughts were strange... I became super spiritual, at the beginning I thought I was given a medicine to check if I was nuts. I started "talking to birds" not literally but as if with their chirping I was warned of things. Like the death of my bf brother at the time. I instantly found deep meaning in books, or would open them to find just what I needed to fit. Since I did love those side effects even if other people felt now I was really crazy, I kept taking it. Even when friends recognized that i was noticeably slow. Until it did what it did. Once I was completely blank and unable to retrieve my memories I stopped, but never went back to normal.
