Not GP, and not battling any major addiction (luckily), but this reminded me when I got fit/lost some weight (~20 pounds or so) a decade ago. I simply (not easily) cut out snacks (candy/chips/sugary drinks/etc) but my main vice was ice cream. So I kept a pint of my favorite kind (mint chip) in the freezer. I don't know how I got the idea, but my reasoning was that it gave me a singular focus on what to avoid, instead of navigating 50 traps, there was just 1. If I was at the store I didn't have to be tempted by anything as I already had my favorite at home. No idea if it is the same idea as GP describes, but it reminded me.
