Be really careful from here... when I relapsed it started off that way (just here and there) and it made me think I could drink without going back to the daily, but it pretty soon went back there. It can be really confusing when you drink a few times without major consequence. (I say this not trying to be condescending -- it sounds silly but having a few incident-free slips really did mess with my head).
Is there something you could get involved with on the weekend that would give you more of the excitement/release that you're looking for? Like some kind of outdoor sport maybe?
