I did an intervention with my AW this past December, she went, then checked herself out 36 hours later and got drunk. Track record: 10 years, 5 detoxes, 5 rehabs -- still drinking.
The main purpose of these boards is for friends and family to find help for themselves. I am trying not to be obsessed with getting my AW to stop drinking. She is obsessed with alcohol, I am obsessed with her use of alcohol (including trying to figure out how to get her to quit). I tried 100 different things and intervention was one of them.
Turning addiction into a medical science problem might make for some interesting research, but I'm not expecting the silver bullet any time soon.
