I have been on topamax for about 8 months. I started with 25, upped to 50, upped to 100 a day, then went to 300. now i have a raging diarrhea that I cannot control. I can't eat anything anymore. I have had seizures and at this point don't care anymore. So yesterday I simply stopped taking it. I am done. I just want to eat something and stop sitting on the stool. My poo has gone completely green at times....that is stomach bile. This medication is terrible stuff and should be removed from the market!
