Hello,
Being a smoker for over 50 years I have seen in a laboratory setting the capillaries constrict due to the action of nicotine, its almost the same as putting your hand over the wind pipe and impeding the flow of oxygen. Most of us smokers don't get the message until our first heart attack.

Or worse, sometimes.

In holland there is a neuropathie center that uses acapuncture and supplements
i have seen a youtube movie of a ex-alcoholist that was threated.
His simptomes where numm feet and the feeling like walking pillows
The first 5 or 6 threadments this guys didnt feel much but after the nummnes disapeard and he began to feel his feet agian,in hs own word it was a big changes
I can post the video but none of you would be able to understand dutch

I feel what you have to go true battling this disease in my case its still not sure what its casing my problems.
I suspect it is alcohol case even if my b12 level was good but having symtomes that are typical for a b12 shortes
Or the use of a medicine like dapsone
