the dragging day

Today just seems as if it will never be over. I'm tired today, even though I slept well last night, and work is not where I want to be. I know that this is not an uncommon feeling among the working folk, but I just can't seem to shake my afternoon slump.

Yesterday I had an all day meeting. I got into the office early and had to be on top of my game for the whole day. It was rough. I think because of it, I'm just worn out. I played Smiley McSuper-Worker all day, and I just haven't recovered. And in comparison to yesterday, today is really slow. There is nothing to prep for and nothing to present, so the day to day work just seems unexciting. I know I need to get it together and get at least a little something done this afternoon, but crawling under my desk for a nap seems like the more appealing option. 

How much coffee is too much in one day?
