I had been doing so well; I hadn't had a bout of insomnia for nearly a month. Why did it have to happen tonight, when I've got so much work ahead of me tomorrow?
(I think I just answered my own question)
Now would be a great time for a "medicinal" shot of Bailey's Irish Cream or Kentucky bourbon, but I'm all out.
EDIT: Luck smiles on me. I found a fellow sufferer online. We're chatting and keeping each other company.
I brewed up a pot of Earl Grey tea. I figure if I'm going to be half-awake, I might as well score some piping-hot caffeine and be fully wide-eyed.
