Meetings are one part of the entirety of my program. I have gone up and down in the number and if I get down to 2 a week, I self-correct the next wk. 4-6 is my sweet spot and right now I'm doing 90/90 again (I am 3+ yr sober).
It's not about going or not going to meetings, the act itself, but it's about how I am working the entirety of my recovery.
Sometimes different meetings ebb and flow in attendance or something else about how they are run or whatever, so I have switched up where I go over time, and try to have a couple different places I go - usually 3 different locations each wk.
