I have one beer a day maybe 4-5 days a week, after everything is done in the house and everyone is in bed. My wife can't drink, and I've just got too much going on to have more than that on a typical night. I really have no desire to feel drunk, or even buzzed, when I'm enjoying a drink by myself. At that point, enjoying a good beer provides all the relaxation I need even without the alcohol.
Don't get me wrong - I'm not a teetotaler. I have no problem throwing a few back with my buddies. But my buddies and I all have small kids, so those opportunities are few and far between.
Needless to say, I never feel the need to take a break from drinking. If anything, I have to tell myself that I need to drink more often, since the beer piles up faster than I consume it.
