Hi Drifting, my experience with Topamax was not long and not so good. 25mg low dose gave me tingly hands and feet, sleepy, did not want to eat and last and worst symptoms was dizziness which is my primary symptoms! so I got off of it after a a few days. Now I know these symptoms may have subsided after longer use but I'm not prepared to do that at this point.

I may ask my doc for amitriptyline as I hear many PCS patients have good results with it.
