When I don't get to the coffee machine, I've been known to plow through a case in three days or less. (No plugging change for me, I work at home)
I've tried to come off caffeine so many times now, I'm just worthless and weak. I don't even know what I wanna do with my life, although I might wanna rock.
(sorry for the Twisted Sister reference - couldn't help it, it's one of those days - at least I stopped saying that "All your base" thing)
