I like the practical, don't over think it approaches. During the lead up to my quit day, I remember reading in the AVRT threads the idea of asking yourself WHO wants the alcohol, for WHAT reason and WHY?- AS you are literally in the process of buying it. Asking yourself, " Is this buying of alcohol just an inane habit?" I used that tactic's answers to literally stop myself mid-buying trip several times in the very early days.
