Hi serendipity
You'll find a lot of people here happy and sober through the 12 steps, a lot of folks happy and sober through other programmes, and a lot of people happy and sober with no programme at all beyond this wonderful community
I'm in that last group and have been happy and sober since 2007
I think this really is an individual decision that goes beyond simple right and wrong answers...but if you're happy and you're sober I think you have a lot of the foundations covered
welcome aboard
