My longest is a week. I was ill and i completely isolated. I was miserable, not because of the lack of meetings but because had i been working my program, I'd have called some friends to come over and cook me dinner etc. So it was the complete absence of a program that made me a bit of a wreck. I used to go to meetings to keep me sober. Now i go to be with my family. In other words, i enjoy them now and there are a few a week that i couldn't bear to miss. But I'm curious: why are you asking this question?
