I used to be part of and helped organize an SOS meeting in Nashville. I have even gone to a few of the National meetings and went with the branch LSR or Lifering Secular Recovery. (There is history, but it doesn't matter). I have had a few lapses over the years, but been 99% sober except for those few. Unfortunately, there is not anything going on right now. There are a couple of mailing lists with Lifering. The information is at:
