All of my rehabilitative assignments have actually taken place a couple of weeks or more after having already put the bottle down. Able to stop, but not in time to avoid the consequences. That experience for me is the worst. Selfishly, It's just a game of how to I navigate my assignment as quickly as possible to preserve my bottom. Sounds like your experience with stopping is different. And that is something that the one-size-fits-all crowd misses and my insanity juggles. But it's also the beauty of the soft language written in the blue book with steps in it.
To your dilemma, I found myself in a similar worry for my first, and only, inpatient. I had genuine concerns that since I had not had a drink in almost two weeks that insurance and the facility would not take. I'm also an extremely honest person. What to do? Only way I could navigate my integrity around the situation was to go to the liquor store, buy some vodka, take the smallest sip known to mankind, and dump out the rest. Obviously not a recommendation, but my switch was already turned off.
When was your last drink? "Today." What did you drink? "Half-pint of vodka." Check.
