That's another side-effect: my sleep has been terribly disrupted. It started really dragging me down yesterday.
On a work note - my entire department has been re-organized. I'm less than thrilled, but trying hard not to get too pessimistic about it. I no longer work for the same manager - I will be working for a colleague that has been promoted. This will be my first experience in my career with dealing with that type of transition. I also now report through a director who I am personally not a big fan of, which is actually what I am more concerned about. So - I think I'm just going to lay low and put my head down for the next few weeks and observe how things start panning out.
