I watched the show you are speakiing about, every single person they had on there that had stayed sober/clean was either active in AA or NA, they had one guy on thier that claimed he was "clean" and when he said that his mother said "Maybe you are clean today!".
I have watched those shows before and the whole focus of the interventions is not to get them into AA, NA, or any other program, it is to simply get the person with the problem into rehab.
My experience was that as long as I was still drinking there was no way I was going to try AA or any other program to get sober. I had to hit the point where the only thing I had left was a detox to get me sober............ Once I got sober via detox, my head was clear enough then and only then to where I could finally see that in order to stay sober I needed a program! In detox they suggested AA, it worked for me.
That particular show brought tears to my eyes more then once when I heard those folks share about thier recovery.
