Tired

I am so tired today. I have theories, but not sure as to why I am so tired today. I was on the computer yesterday afternoon and evening. From 4-8pm, I was not in the recliner yesterday. I took my antibiotic around 10 pm last night. I took Bendryl around 11:30 pm, and went to sleep around 12:30 am. (I took the Bendryl, because the area where the port was placed, itches.) I woke up a couple of times in the night. I woke up around 7:30 this morning, so tired, that I went back to sleep until 9 am. I even tried taking a nap before lunch today. I feel tired.
