So, I hope that was just from lack of sleep

Had a store meeting yesterday.

Tried to get some sleep before it. Didn't really get any.
Tried to get some sleep after it. That didn't work too well either.
Went to work, with a headache from not getting much sleep. Took Tylenol from my stash at work. Realized that said bottle of Tylenol was Tylenol PM. So, felt sleepy at work.
Came home. Was sleepy. Got something to eat, went to bed.
Got up a couple hours later, went to the bathroom, and fainted. At least, I assume I fainted. I don't really know, but I don't have any other explanation.

Going back to bed now.
