I'll only drink coffee one way: cold, in mixture of milk, chocolate syrup, and sugar. Otherwise I find it disgusting. It's actually not that bad, pretty much like chocolate milk. I experimented with that combination one night when I had to pull an all-nighter. Sure enough, it kept me awake, but I was insanely hyper and delirious that day, running only on pure caffeine and sugar. XD
I've never drunk coffee until this semester, really, because I'm finding myself having to function on less sleep. Not even really much less sleep, but having to be up and running at an earlier time. I'm a night person and can't function well in the morning, regardless of how much sleep I've had. I only drink my concoction when I'm really tired and need to be alert (i.e. before class), so, a few times a week. Before this semester it was "never," other than only that one all-nighter.
