It wasn't a cold. It was bronchitis. The bacterial sort, rather than the viral sort. The cold I had led to a bacterial superinfection that is now getting its butt kicked with Spectracef (note: Spectracef is one nasty drug).
I slept all day today. *All* day. As in, I got up at six to pee, drink a cup of coffee, and eat some toast, then went back to bed. Got up at one to do the same thing, then went back to bed. Got up at six-thirty this evening and am waiting on toast right now.
So if I'm not around much in the coming days, that's why. The good news is that I feel considerably better. The bad news is that now everybody else at work has this, too. *sigh*
