Have your B-12 levels been checked? I personally have wondered the same thing. I am in my early 50's, fit, and do not typically drink during the week (unless a special occasion), but was having more than the recommended 1-2 drinks on most weekend days while watching games or out with friends (mostly light beer over several hours and always with food and lots of water before bed). I know many people who drink a whole lot more with no issues. For 4 months I have had common symptoms of neuropathy (have not been officially diagnosed yet), but I do not have incontinence. My B-12 levels were low and have improved significantly after taking supplements, but the symptoms persist. I have cut my weekend alcohol intake in half or more, am limiting caffeine, and focusing on more healthy eating habits without banning anything. I did ask my neurologist about this and she sort of discounted alcohol as the cause, but I have not had any testing to confirm this. She is leaving the area and I see a new doctor next week. I work hard and exercise during the week and enjoy social interaction with family and friends at meals, games, concerts, and breweries on the weekends . I have such anxiety over my symptoms that having a drink or 2 helps me to relax a bit and feel normal, yet I constantly worry about progression. I understand your feelings and empathize.
