I am that fellow that MrsD referred to above. I am an alcoholic, albeit a sober one. I drank for about 20 years daily, now I am 440 days sober. I pretty much went from a healthy average sized person to a drunk in a wheelchair. If you follow the thread on that you will see that 3 things worked for me. One, I quit drinking and started eating. Two, I forced myself to exercise a little bit a day to keep the legs moving and three, I took MrsD advice and went on a vitamin regime of:

Centrum Men Under 50, Multivitamin, 200-Count Bottle
Doctor's Best Benfotiamine (150 mg), Vegetable Capsules, 120-Count
Jarrow Formulations Jarrow B-right Complex, 100 Capsules

I am now walking without my cane most of the time, can work FT and I feel great.

Now, I dont know what percentage of PN sufferers beat it, but in my case I pretty much did. I will most likely have many lingering effects over my lifetime, but where I am at today beats the hell out of where I was 1.5 years ago.

Stay positive, force yourself outside and you have a chance! I am walking proof of that.
