When I was a couple of years sober I asked my grand sponsor with 30+ years why it seemed that some people with serious time on the program stopped coming to meetings. "Do they all go out and drink?" I asked.
He said "Some probably do and some get just well enough to stay sober without the meetings."
And then I asked him why he keeps
going back and he said, "Some people are satisfied with one bite of the
cake, some people are satisfied with one piece of the cake, but as for
me... I want the whole damn cake."
