I spent some time in the corporate "boozy" world a few years back. Din't impact my sobriety at all. In fact being sober won me lots of business and customer loyalty that the drinking brigade missed completely.
I made one or two observations. The hard drinkers were less effective, and missed opportunties. The smart ones, like the boss, only appeared to be drinking. He had this knack of sitting on one beer all night. Maybe that is why he was the boss.
