Ed,

I also have problems with weakness and fatigue. I take Neurontin too. I've heard Neurontin can cause fatigue, but so can PN. Maybe adjusting your dose would help? Also, I know there are several meds available for fatigue..Provigil and Amantadine (older med).

I had luck with an Occupational therapist. She showed me different ways of doing things that conserved energy. I also had some exercises to help strengthen my muscles.

Good luck.
