In my first couple of years of recovery I went to as many meetings as I could. I needed that because I had no clue how to live without drinking. I did not know what to do with my time. I needed the support of people who had been through what I was going through. I needed to build a support group in recovery. I needed to learn how to work the program of AA. One thing that I figured is that I spent more time drinking in a day than pretty much any time AA took out of my day even if it was several meetings.
For each person it is different though. I do know people who went to one meeting a day or a couple a week in early sobriety and seem to be doing fine. I have 10 years sobriety and still attend at least two a week. I guess it just depends on the person.
