It finally happened.  After a few years of not getting any sort of virus, I caught a simple head cold.  It knocked me completely out for three whole days.  I am still all stuffy and have the intermittent sinus headache and remain within 20 feet of a tissue at all times, but I am feeling okay.  I just didn't think I would get knocked out like I have.  All in all I handled it pretty well, with the help of Nyquil of course.
