Heather....that's AWESOME!!!
I assume your IDRC program is similar to one here in Mich I was sent to for a Friday-Sunday stay. (It was in a hotel, we were bed-checked during the night, and it was run by some folks who work/run a treatment center here in Michigan). I was mad about going and even more mad that I had to pay for it (think it was about $400).
It was one of those life-changing events for me though. It was in that "class" that it finally dawned on me that I 1. had a drinking PROBLEM 2. that I was almost certainly alcoholic 3. that I better do something about it or it would get worse 4. that AA does work....and that it might even work for me. I too "surrendered" to a lot more of my reality than I probably ever had.......and it was a WONDERFUL experience as far as my path to sobriety was concerned.
