anxiety medication

Has anyone ever taken the medication topamax (generic version) for their anxiety? It has caused me side effects of naseua and diarrhea for about three weeks now every morning. I'm taking 100mg (50mg in the am & 50mg in the pm). I didn't know if anyone else experienced these symptoms too. I've been taking it for about a month now. If anyone could help me out with any ideas of what could be wrong, that could be great!
