I've gone months before. Two to three weeks to a month is common for me, maybe the norm. After college, I've never been compelled to drink daily. Hell, even in college, when I would let it rip multiple times a week, I was never someone that could get drunk seven days in a row or anything like that.
I have no problem going without alcohol...my issue, insomuch as I would ever have one, is that I'm not good as a moderate drinker. Very hard for me to have one beer and not have ten. Even now, put me in a drinking social occasion like a wedding reception, and I can get to double digit drinks pretty quickly. Just not good about saying no after the first one. I have to really check myself at work functions with alcohol, which only became something I started dealing with at my most recent job...not always successfully.
I've really only mastered moderate drinking in recent years as my kids got older, so that they could see there was such a thing as moderate or social drinking. Before that, I just wouldn't drink in front of my kids at all, but after they went to bed, I could sit and drink alone and excessively (once every few weeks).
