Hi Joe, Alcholic Neuropathy patients are normally tested for Thiamine deficiency [B1], but one beer every now and again, does not put you in that catergory, no way known.
The sugar in beer can aggravate already damaged small fibre's, which are the ones responsible for feeling of sensation [heat, cold, pain, numbness],
There are many, many reasons why people get small fibre damage, perhaps you need the services of a neuro that specializes in PN, particularly a small fibre expert, they will send you for all the necessary tests you need to hopefully find the cause and yes stress, anxiety can aggravate the nerves but finding the underlying cause why your nerves are damaged should be investigated, even your General practitioner can order some tests, like a 3 or 5 hour glucose tolerance test for impaired glucose tolerance, heavy metal toxicity like Arsenic, Mercury, lead with a urine test, etc, but really a PN expert is the best option.
