Is your friend taking Topamax?

I started developing stones while taking the Topamax, and was told to increase the clear liquids. I finally had to stop taking it due too the stones, hair thinning, and eye problems. It was to bad too because it really did work.

Not sire if RSD can cause the stones problem, but wouldnt be surprised that diet of your friend would be altered because of RSD, and cause the stones.

Maybe someone else has more to add about the RSD part.
