There's something about it that screws with me on a physical and mental level.

It's basically the sense of having done a lot of things, then needing to face a shift of work. In ideal circumstances I just prefer to wake up and get work out of the way.

But there are those days where I drive to a park, take a walk, run some errands...and my work day is ruined. Too overstimulated.

Not sure if this is an anxiety thing or not.
