FT,
Yes, what you did is not incongruent with the AVRT concept of shifting. Another example of how this approach differs from conventional wisdom. In traditional treatment, what you did would be considered insane, dangerous, a warning sign of relapse, a slippery place, etc. AVRT is recovery with an attitude, though, and goes straight for the jugular to get the job done right.
If you hesitate to kick your Beast's ass, it certainly won't hesitate to sacrifice you in order to get its fix, so why show it mercy? In fact, it is better if you enjoy kicking its ass. Be ruthless - it's payback time! What is it Trimpey told me yesterday? Something along the lines of "if you're not having fun with AVRT, you're not doing it right."
In that vein, I do hope this thread stays lighthearted and doesn't get too boring. :-)
