I did not have success in 12-step programs so maybe my perspective is different--but it does seem to me if you really want to be clean, then you are willing to try ANYTHING. If you want to find loopholes and reasons to avoid certain tactics, then maybe that points out where a real underlying problem is.
Going without a relationship for a year is pretty common, so it is not as central to life as eating or breathing. But I have encountered many people in recovery for whom being alone is difficult. Maybe this is just another aspect of the addiction.
Admittedly, I am not in a 12-step program, so I may be too willing to grab onto ANY idea that can help. But I think this is a good one--even if you are in the fellowship.
