Thanks, SunshineSally. I completely forgot about the AVRT crash course, which I haven't looked at in a very long time. I do recommend that people take the free crash course as well as reading the book.
Oakwood, although I tailored my response to freethinking's situation, I was thinking in general terms of the typical bargain situation, whereby people create a necessary condition for abstinence. This, of course, naturally also creates a condition to drink. A general maxim to remember is this:
"Your desire for any special conditions in order to abstain conceals a plan to drink/use in the absence of those conditions."
