I don't remember having that problem when I was on Topamax, but could be. Is it causing you to have breathing problems, if so you may be becoming allergic to certain smells. My mother got to where anything that had a strong smell would make her need her inhaler. Perfumes were really bad. She finally quit going out in public.

I would check with my doctor and see what he says. He may have an answer.
Best wishes.
