At 87, if you haven’t licked alcoholism, chances of beating it are between slim and none...and Slim just left town.
does it matter at 87? my motto is after 75 do whatever you want
It would amaze you how long a drunk can live. What normally kills them is accidents. We have a cousin who smokes Weed all day and drinks all night. He’ll probably outlive us. He eats well, play golf almost every day and grows a garden.
Also, when a drunk stops eating, find them a plot.
