when i went on a short term mega dose of mostly b-vitamins, i got my position sense back in couple of days. but, it doesn't sound like you have those problems in particular.
the hypersensitivity lasted a lot longer and i'm not sure what got rid of it, except major changes in my diet taking effect over about 6 months post-dx. oddly, sometimes when i would take b-complex the hypersensitivity would increase temporarily. i think the magnesium has helped resolve that problem, they're just asleep now. although the fingers do feel a bit puffy today. i have been bad with the vitamins over the last week :S
i have a bulging disk in my neck, never mind the lesions, and my dx attack was associated with a bad snowboarding crash without a helmet, which i think is why i can't get them all the way back to 100%. i have to make more concerted efforts to get that disk off my spinal cord and back where it belongs!
what's your supplement regimen, if there's anything that jumps out at me as being missing, i could let you know.
