I've been sober 38 years and try to get to one or two meetings a week. Sometimes I might not make it for a week or two, but that's because I'm just to busy. My sobriety is not contingent upon my meeting attendance. It's because of The Twelve Steps and maintaining my spiritual gratitude.
I'm not religious so meetings are a place where I can really take time to reflect on life, and maybe even help someone else.
I know quite a few people who no longer attend meetings and are doing fine. I know a lot of people who go to meetings daily and are doing fine. I also no the case vise versa where some peoples lives are a mess going daily to meetings. And, many more who I never see or hear about again.
The scariest thing is how fast 30 years go by. Life is short, make the most of it. I've found I get more out of life by giving more that I take.
