I'll just note for clarity that I am referring to the "playing the tape" or "remembering your last drunk" approach here, in which one tries to recall the downsides of drinking in order to deter oneself from indulging. The Beast isn't interested in drinking for the downsides, however, and in fact, doesn't even take them into account.
The Beast is only interested in
the benefits of drinking. Thus, in AVRT, we become just like the Beast, and
abstain from the benefits of drinking, not from the downsides. The Beast would not be deterred by the downsides, in any case. It is a rational sociopath which drinks to live, after all.
