Exhausted

I have an interested story to tell about my weekend but am too exhausted right now to do it coherently. The crazy weekend and very long days in the lab/office have left me without much energy. I've been dizzy for at least an hour today. A couple of weeks ago I "saw stars" while I was cooking dinner. I never really believed people when they said they saw stars but now I do. It was like a bunch of flies buzzing around my head that had little lights attached to them. I'm worried that I am not eating enough or am doing something wrong. Anyway, will write more soon.
