Yes, I have stopped going to meetings before but I go faithfully these days because I didn't like the results.
If for no other reason, going so that one has reliable connections if they should need help is a good idea.
Then there's that pesky little notion that going when you're stable is a way of paying back what you have been freely given. Poking at you a bit, here.
To be less frivolous, I do know some old-timers who are unable, especially in the winter time, to get to meetings any more. And they maintain sobriety. Don't know what the quality of it is, though.
Some people do make the decision after a period of time not to go anymore and that's their choice. I just keep in mind what I've heard hundreds of times. That people say they relapse when they quit going. So for me, better safe than sorry.
Also, I LIKE the people I hang out with at meetings and look forward to spending a few hours a week with them. My Friday Happy Hour group is at least as much fun as I've ever had in a bar.
