Not everyone does 90 meetings in 90 days...it only took me about 70 days to do that
Of course, I still went out and got drunk anyway
And of course some people come in for 1 or 2 meetings and never come back.
I do think a lot of your sentiments are normal. Small talk certainly takes place before and after the meeting, but I don't consider the sharing part of an AA meeting small talk.
90 meetings in 90 days is really to get you used to the atmosphere. Early on when everything is new, we are so busy trying to get comfortable in the new environment and getting used to being sober, we often miss the message. So 90 in 90 is a rule of thumb that has evolved over the years.
"too much hand holding"? Are you kidding? The only time I have see people hold hands is at the end of the meeting for about 30 seconds. If that's too much to help solve your alcohol problem I don't know how to respond.
