My alcoholism (if it can be called that - it is a spectrum) is driven in part by the social interaction of fellow drinkers. The predictability of seeing each other at the bar, of hanging out and not worrying about the day.

I've talked to one or two of them about doing tea on Tuesdays, or some other thing that could get us from drinking 3-7 stouts a night.

That book may be worth a read.
