IMHO, this is a very important point you make, Sam.
I would not directly pressure him about his sobriety. That just doesn't work. You can't control his drinking.
From what I recall of your earliest posts, your dropping the rope and GAL work did have a positive effect in the past, so maybe that is s/t to consider.
What might be some specific GAL goals for you to put into play, as soon as today?
