In my profession, weekends are busy work times.
But your point still applies -- "down time" is risky time. I'm past the point of missing alcohol during down time, but the void of down time is vaguely uncomfortable. I'm considering taking a little part-time job in the evenings to alleviate the boredom.
So here's my idea: For folks who are struggling with weekend or evening sobriety, why not take a little part-time job for a while? It's not forever. And you'd pick up a few coins.
