Nov 5 2008 I have been taking topamax since april of 2008, about...

Actually, anxiety is a negative side affect of Topamax (usually meaning to high of dose or the body is not tolorating the medicine at all).. Topamax has only decreased the serverity but I still usually have a chronice everyday migraine. Its possible that the 75mg is to much for you.. when Im on 100mg it does the same thing to me.. My neurologist said to take the medicine at night before bed.
This is just my experience, good luck!

Topamax nearly drove me crazy and I'm very serious. It took me a month to figure it out but it was pure hell. The awful thoughts that went on inside my head - suicide, especially - obsessive behavior towards a person very dear to me, anxiety, and I knew it wasn't me! I couldn't get free of it. I'll take the physical pain over the mental anquish any day.

I have been on Topamax for a little over one year. I was up to 75 mg. and had to drop to 50 mg. due to body aches and nervousness. My migraines have improved and I used to have a daily chronic headache as well. The problem is I have increased anxiety that I cannot get rid of either. I am still nervous with anxiety and around the time of my period it is much worse. Doctor gave me Xanax but it only helps for a few hours and then it comes back. I'm afraid to get off the Topamax because when I started to step down to 25 mgs. the headaches started coming back. I am thinking of adding another drug like Effexor or something but I hear and read a lot of stories about the interactions with Topamax and other drugs and I'm not sure what to do. Sometimes I think maybe I should come off of it and just try Zoloft or something else. I have also lost about 10 pounds and can't gain the weight back. Permanent appetite loss.
