FATIGUE?

What in the world is going on?!? Since I have been here I have been feeling fatigue and even sleepy everyday around 1 p.m. and no matter what I do, I can't seem to fight it. It is driving me crazy.

On Monday all of us were in the office and I tried moving around walking outside and just whatever but to no avail! I'm not sure what sleep-walking feels like but I gotta wonder if it is close to what I've got going on right now.
