I too, have alcoholic neuropathy.
Good work on being sober for as long as you have.
I've never joined AA, went cold turkey and stayed off 100% for 5 years.
Now I take a drink occasionally, but have found that I suffer for it.
The PN flares up-so PN & alcohol are a bad mix, if you want to recuperate.
Supplements are very important, as the alcohol has depleted your normal levels, drastically.
B12-methylcobalamin, (not cyanocobalamin) sublingual- is effective at 1000-5000 mcg/day. Vit C, folates (folic acid), ALA (RLA), CoQ10, Omega 3,6,9 Fish Oil, and a few others you'll hear spoken of, on this forum.
Lots of sleep-at least 6-8 hrs a nite.
And meds. That will be a search for the right combination to best serve your needs. Many here are taking Neurontin or Lyrica along with a pain killer, like Ultram.
You and your neurologist will have to do trial & error until you find your 'cocktail'.
It will take a long time to see results with supplements -months or years.
The meds should help in the short haul.
