fewer NA meetings, and the Saturday-night jones — "the regular from 2100 to 2200h…"
the regular from 2100 to 2200h., purposely late, to offset the Saturday-night jones so many drug addicts suffer weekly, Saturday still being the week’s special mythic Party-Night even for persons who long ago ceased to be able to do anything but Party 24/7/365
Context
The recovery infrastructure's fine grain: NA has fewer meetings than AA, and the North Cambridge group runs late on Saturday on purpose — timed against the "Saturday-night jones" that grips drug addicts weekly, Saturday still the mythic Party-Night even for people who long ago lost the ability to do anything but party around the clock. The scheduling is doctrine made logistical, the fellowship building its calendar around the specific hour the disease bites hardest.
