I suppose cabin fever would start to set in after a certain point.

I think it helps that I usually have these thoughts at work, when I'm shivering in my cubicle, thinking, "man, wouldn't it be awesome to be at home, under a blanket, reading a book?"

(Maybe I can bring an afghan to work and curl up under that. My office chair is plenty big. And there's powdered hot chocolate in the coffee mess.)
