Feeling not so good

I promised myself that I would start writing today. Yeah, riiiiight. I spent most of the day reading novellas I downloaded from Ellora's Cave and Amber Quill. Then I tried to do some writing tonight, but I had to stop because I'm not feeling well. My stomach is upset. I can't think of anything I ate to make my stomach this upset. Unless it's my hypoglycemia acting out...again. Sheesh!
