I shouldn't complain. I haven't taken a sick day since before Simon was born, other than to stay home to look after him and/or Diana when they were sick. Alas, something has decided to kick my ass today.
The worst part of it is that your sleep gets all screwed up, and you feel crappy but can't do your best to sleep it off since you were napping or whatever. Sigh. This is not what I had in mind when I said I wanted more time off.
