Welcome bottleslave - good thread.
I am a SR-only member and so far (~ 80 days) it has worked and worked really well. There are so many ways to get support here - forums, chats, private messages - people are so present for you as you get this sobriety stuff going.
I had tried AA, LifeRing, Smart Recovery, Moderation Management - all these groups and none of them worked like SR for me.. I do however use the literature from all of these groups - have everything from the Big Book to the handbooks from LifeRing and Smart Recovery on my "recovery shelf" and read them a lot. Also have gotten a lot of support from a book entitled "Changing for Good" - I use that program of change as a backbone of getting sober.
Welcome and good luck - look forward to having you here!
