But what do you call it when you do have stable moods between episodes, that just don't last very long? The lengthiest period of stability I've had was 2 months, and that lasted from early Agust to mid-October before the choo-choo went off the rails again. Isn't that rapid cycling? My pdoc seems to think so, although personally I don't reall care WHAT the hell it's called, I'm sick of it and I want to go back to where I was in the late summer and early fall when I felt totally normal.
