For what it's worth -- I didn't quit until I was 61. That's an ocean of booze over the years. I think I had every possible physical complication from alcoholism when I finally stopped for good over two years ago. 😮
Gradually over the last 28 months my body has been healing itself and been doing a damn fine job albeit slowly. I am pretty sure I shortened my life span but I don't have a crystal ball and I am not going to worry about. I stopped drinking and am doing what I should in the way of lifestyle. Other than that it is out of my hands so I don't fret about it.
I am sure the consequences of the drink will always be with me to some extent but the trajectory now is up instead of down
Remember, getting and staying sober is a process not an event.
