I tried the NA beer method to cut back some time ago. Didn't work for me, probably because part of it was about the ritual of drinking - taking the bottle, taking a sip, putting the bottle back etc.
Used to think drinking NA beers was similar to taking a shower with your clothes on - you do get wet, but achieve nothing in terms of what you went there to do. Think it's different for people, for me, the cravings would skyrocket
