Ever have one of those days?

Have you ever had one of those days where no matter how many mini Hershey's bars you eat you just can not wake up? Yeah.. I'm having one of those days. All I want to do is go back to sleep. I just don't seem to have any energy and am not sure why that is.

Unless I forgot to take my vitamins... hmm... think I have forgotten them. That would explain a lot. in articular why I just have no energy and minimal focus.
