I can't imagine going to 90 meetings in 90 days. I have been to aa a number of times. I went a few times a week for a couple months and going 90 days in a row would make me want to kill them.
I really think it depends on the groups you get. Mine were filled mostly with old men regaling us with anecdotes of their drinking days and chuckling about inane in-jokes and big book wisdom.
If I were to choose between attending 90 meetings on consecutive days or slamming my junk in a car door repeatedly, the meetings would win. Just.
Different strokes and all.
