Psychomotor Agitation I think it referring to just being overall fidgety. Like when you couldn't sit still to save your life and feel the incredible NEED to get up and move around.

A few other points:
I may get between 3 or 4 hours of sleep a night (maybe less) per night for a week or more. And I won't even be tired. In fact, I'll probably get more accomplished even than I normally would.

Being more talkative: This is more evidenced when I'm in a meeting at work or something. I have an extremely hard time not inturrepting when other people are talking. And when I start talking, I feel a need to continue to talk. Even to the point of being embarrassed by it, but there's something that almost feels like I NEED to do it.

- You experiece a flight of ideas or feel your thoughts are racing.
To me this is almost a dizzy feeling. Like drunk almost.

-You are easily distracted.
(Can I just say that I've been working on writing this post out for about 3 hours... and just leave it at that?)
