When I have a drink --whether it be beer, wine, whisk(e)y, or cocktails-- I like to sit, relax, and enjoy it. So, depending on how busy I am, I routinely go for days without alcohol. I don't really keep track, but I'm sure it's not unusual for me to be dry for a week or more at a time. I doubt there have been many times when I've gone for a full month, but as I say, I'm not keeping a record.
On the other side of the coin, I also don't place any particular constraints, per se, on myself when I do drink. But that's not really a problem because I HATE the feeling of being drunk (or even tipsy, really), so there's never any chance of me drinking to excess in the first place.
