Mine is not S/F however it has progressed a few inches per year until recently where something startling has occurred.

alpha lipoic acid!

3 weeks on 600mg/day and the last 4 days my PN went into total remission. Possibly the happiest few days of my life. Numbness was still there though but much less number (is that a word?)

Last night pain bounced back to 4-5 however this morning its back to a 2

I have delayed buying this stuff for years because it expensive at $30 (australian) for 60 at 300mg

Am trying to find a new source, what do you guys pay for it in USA?
