Phantom symptom apparition

Okay, I am seriously sleepy right now. This started around noon... I had a cup of tea with a colleague and when I left her house I almost wanted to pull over to the side of the road and take a nap, even though I'm pretty sure that was a caffeinated chai I'd just drunk.

Right now my husband is at the movies with his brother (Wolverine = me not interested) and I have to make it three more hours until he gets back to eat dinner. I am NOT a napper and I've filled my caffeine quota for the day. Oh, what to do. I'm tempted to read a book, but then I will definitely fall asleep and start cannabalizing people's heads when I wake up (why I don't take naps).

Maybe a dumb computer game will get me through.
