Hi,
I read that the peripheral nerves transmit signals between the body, the spinal cord, and the brain. Thiamine, folate, niacin and vitamin B6 and B12 and vitamin E are all needed for proper nerve function. And drinking too much can alter levels of these nutrients and affect the spread of alcoholic neuropathy.
Things that are in moderation are just fine but we all know that everything that is too much is bad. Hope this could help.
