This is just my opinion, but I don't think "AVRT" is under-practiced at all!
The reason you don't notice it is that people who quit drinking alcohol on their own do so pretty silently, no fuss, no muss, no fanfare. No group.
Coming on here is as "out there" as I ever get. I may sound loud and opinionated here, but you'll never see me out in public or at group gatherings proclaiming my sobriety.
Just my opinion, but I don't think I'm alone.
