sick again

It feels like every time I turn around I'm getting sick this year. I have had two colds already and the stomach flu and now I'm feeling crappy again. This time it is possibly the worst sore throat I have ever had. I have sick leave at work, but I always feel so guilty when I call in. I try to tell myself that it's better to call in, especially when you consider how many of my coworkers have babies and very young children or pregnant spouses. I don't want to get anyone sick, but I also feel like I've been calling in every couple weeks. I guess I should really start taking vitamins. I just wish they could make vitamins come in a smaller format. I mean, is it really necessary to make them the approximate size of an asteroid? Ugh.
