OP, you've described very well what I feel from time to time.....like now. Most of my manic episodes are euphoric, grandiose, soaring; but then there are times that I'm restless, agitated, angry, upset, irritable, and wired. Like now. It doesn't feel like mania, though my test scores on the Mood Tracker and Mania tests are very definite about it, and yet I'm certainly not depressed, for I don't have this kind of energy when I'm in that state.

Thank you for defining this phenomenon so well. Maybe I'll copy and paste this description for my next e-mail to my pdoc, if you don't mind, because I can't articulate it as well as you have.
