I would have to treat my anxiety some other way; that would drive me crazy too. I know when I got home from the hospital after an operation I had a weird smell thing going on and my poor husband had to change the bed sheets 3 times (and wash a set too) before I found a set I could tolerate. It was only then I figured out it had to be the meds throwing off my sense of smell.

SnakeCharmer has an idea with the Zinc. I'd go to my regular doctor and have blood/urine tests done to check all my vitamins/minerals and other things to see if something could be helped there or if something were badly off so I did not want to be on the Topamax because it was interfering with other natural systems.
