Welcome to NT, Kryptonite! Sorry for your troubles, but sounds like MS to me (not a doc though).
I started taking Amantadine about 5 weeks ago to help with fatigue. So far it has helped quite a bit. I mean, I don't roll out of bed ready to set the world on fire, but at least I can accomplish a few things during the day without feeling so "lazy."
Good luck to you. If you do get an MS dx, I expect to see you around here, k?
