I never had a problem. I still imbibe, and enjoy wine with dinner, and an occasional drink when I feel like it.
I can count on one hand the times I had too much, and have fingers left over on one hand. Had three relatives that were alcoholics. I never comprehended why one would want to do that to oneself. 2 of the 3 were in the same hospital, and on the same day, doctors indicated neither would live through the night. Both did, one for nine years, the other for 25 years. The one that got 25 more years stopped drinking completely.
There is no question, drinking in excess shortens one's life. Even if you live to be 100 years of age, life is short already in the grand scheme of things, so why hasten death? At 70, I know I am on the downside of life, but I hope I get 20 more years, and I will gladly take 30 more years if I have my health and mind.
