Getting sick despite my best efforts not to

Despite my best efforts this week, including working away from home and taking lots of Vitamin C, I seem to have caught Keisha's and Jennie's cold. I'm sitting here in the office, feeling a serious draft. All of a sudden, my head starts feeling stuffy and achy. My coworker says that he can tell something is going on because my voice sounds different.

I went to the restroom and blew my nose - nice and green. I came back here, and now I don't feel like doing anything. Yuck.

I want to call Jennie and let her know.

Update: It appears that, after some sinus medicine and a good night's sleep, that I'm better.
