I posted here ages ago about a friend of ours who was shuffling his feet. I suspected neuropathy. He had been heavily drinking for decades. Recent years was very bad. People here did not suggest neuropathy, but I felt that was likely the cause. He passed away. Alcoholism is a terrible disease. I'm not sure if folks can "cut back." Best guess is that is a rare exception. The great majority of folks probably need to completely stop. Awareness of how it affects one's health and overall life is crucial. And I mean "negatively" affects. And often an important wake up call. Blessings.

I am sorry about your friend.

I used to drink a lot but do not regret my healthy choice which I do not regret.

Best wishes.
