[spanky (aka Lola)]

I have felt the bored or unhappy feeling when on a break as well. For me it is "flat" feeling, like I've learned that something I was anticipating is in fact not happening. That possibly could be more of a reaction to knowing that I have changed my routine rather than a biochemical response to the change.

There are also some physical sensations or sensitivities that dissipate as Miss C notes. I always miss those. Finally, I tend to be grouchier on breaks.
