Tom, it is pretty unlikely what you had was the flu last year. I caught it in San Antonio in 2007 and it was terrible. I was working as a supervisor on an outdoor construction site for the first 3-4 days and all I wanted to do was lay in my truck with the heater on. When I got back to Houston I missed 3-4 days of work. When my wife caught it from me, she was off work for a solid week, and it took both of us another week or two to really start feeling normal again after that.

Needless to say, I got a shot a couple of days ago.
