When you're sick, and you feel a lot better, so for a couple days you resume your normal activities... only you weren't actually better?
Of course you do, because, like me, most of my readers do the same thing.
You get a HELL of a lot sicker than you were before.
That's what I've been for the last week. A hell of a lot sicker than I was the week before last.
Still am actually, probably will be for another few days.
