My late AH was told to quit many times by our doctor. He managed to justify it all away. Kept drinking and it did kill him.
He was on very high dose anti-depressants, anti-anxiety tablets as well as other medications for the damage to his organs the alcohol was causing.
Our doctor tried him on several different types of anti-depressants over the years but none worked. But the real issue, of course, was the depressing liquid he was pouring into himself everyday. Also his outlook on the world. Blaming outwardly instead of addressing his inner issues and healing his traumas. Having no other coping mechanism than his wine/whisky.
Once I did my inner work, my whole world changed.
