I have no good reason to be awake at this hour. Would, in fact, prefer to be asleep. I need to go to work in the morning, after all.
I could apply alcohol to the problem, but that would make the whole getting up and going to work portion of the problem, well, problematical.
I shall see if perhaps a bit of loading up on simple sugars and the subsequent crash will be enough to take me off to dream land.
(Though the prospect of re-joining last-night's army dream may be playing a part in this proto-insomnia. Nah, that was mostly fun.)
