After perlgirlju came in, I went back into my office to put away the key she gave me. At that point, I was overcome with a rather nasty dizzy spell.
It hasn't really gone away, and it's been probably an hour.
I'm still functioning alright, but if this keeps up after lunch, I won't be able to stay at work.
Weird, I've never felt like this for this long.
Here's hoping I'm just hungry.
