I went to meetings pretty regularly for the first 5 years of my sobriety. I'd say I averaged 4-5 a week that entire time. Since then my attendance has gone up and down. I went one year with going to about a dozen the entire year. I believe it's the 12 steps that keep me sober, not the meetings, but the meetings help to keep me grounded and happy. What's always been most important for me regarding meetings is that I go to ones I'll benefit from. Bigbook and step meetings are pretty much all I attend now, and they've made up probably 80% of my meetings over the past 30 years. I don't feel I gain anything anymore attending meetings where people are simply discussing their problems. I can be there to give service, but that's about it.
