So, Am I Still Sick, Or Am I Just Lazy?

Still haven't decided whether I'm going to go in to work tonight. I keep thinking I feel a lot better, but whenever I'm up and about for an hour or so -- not even necessarily doing anything, just being vertical -- I get all tired out and want to lie down again for a while. So, yeah, maybe not.

It's odd. Except for the one bout of flu where I was knocked out for the better part of a week, the times I've been sick over the last year or two seem to have followed roughly the same pattern. Day 1: Feel fine most of the day. Develop a slightly scratchy throat by bedtime. Day 2: Wake up after very little sleep feeling like complete crap. Headache, sore throat, general achiness. Terrible congestion that actually clears up considerably after a few hours, especially with the help of a little pseudoephedrin. Day 3: Symptoms mostly gone, still some headache, but very tired and listless and weak. Day 4: Pretty much better. I'm not really complaining about this. It could be a hell of a lot worse. But it seems strange, because most of the colds I've had in my life have been annoying, lingering things with much more pronounced symptoms.
