My AH went to a few weeks of something called 12 in 12 this fall... the deal was that you "do" all the steps in 12 weeks and then you're "cured".... Seemed ridiculous to me and he went for 3 weeks and said it seemed ridiculous to him too. People just read the steps and the leader said something like "does everyone agree we've completed the step" and everyone said yes and it was on to the next step.
I think that he went to it thinking that it was a quick fix, easy solution and when his couple weeks netted him "nothing" (in his estimation) he gave it up.
