another sick day

I am not sure if I've ever taken a sick day before yesterday. Although I've been working for a long time, prior to October, I only had a job which provided sick leave for 3 and a half years. Most of the time I either worked as a contractor or in academic jobs which didn't offer sick pay. Now I've taken two sick days in a row. Not that I'm getting used to it, but I may need one more before I get back to work. I feel good enough to do my work but not good enough to drive there and sit around all day in the same room.
