Sleepy and the sleepy

My energy is well, low, which sucks. But well, I'm tired. And yet, and yet, I've got a good deal of work to do. But the situation remains as it is, and despite my lack of energy I must still work on. Still it occurs to me that eventually I might have to deal with my chronic lack of energy. Perhaps I'll start taking a stimulant, especially since I'm already sort of self-medicating with caffine. But for now, I'm just working tired, I'm still driving but at least I'm not operating heavy machinery.
