I drink so rarely these days. I can go weeks or even months without having a drink. I rarely have anything in the house (actually, that's not true - I have a full wine-rack and a few expensive spirits but nothing I would consider opening "just because").
Very occasionally, if I'm doing a big shop, I might pick up a few bottles of beer but they'll be gone within a couple of days. Can't remember the last time I did this though.
I really don't go out drinking these days either. Nine times out of ten, I'd rather drive than have a drink. I'm at that point in life where all my friends are married with kids and nobody goes out for a session anyway.
I'd say more months than not, my intake would be zero but every once in a while it'll be a few drinks here and there.
