I don't seem to have the mental fog that some people feel with it. We started me on a low dose, and now I'm on the highest dose allowable.

I get a lot of breakthrough pain when it's hot outside. I use anti-inflamatory meds for that...

Today I am home because I am starting to get a lot of "body aches" all over. Like joint pain, not in the bones, but in the muscles around the joints. Can't figure that one out, but the Topamax has helped with the PN pain.

Good Luck!
