It would be an unfortunately incorrect assumption that we don't cycle on meds. Sometimes we do. I read something once that stuck with me -- that BP is "a moving target". So while things may stay steady for various amounts of time, they can also change, which is why we sometimes have rather frequent med changes.

As far as what you describe, yes, that could be hypomania, epecially if it's out of character for you. It's worth paying attention to one's particular indicators, as they tend to differ a bit from person to person. That way, you can catch it early.

Some other indicators for me are intense impatience --everyone is so slow and stupid!-- get out of my way and try to keep up people! I need everything NOW. I strike up conversations with strangers a ton where normally I don't talk much at all. I lose my verbal "filter" and speak before thinking. Things often come out unintentionally suggestive sounding. That's a few that come to mind... oh, and cleaning at ridiculous hours of day and night (with Q-tips and dental tools, no less, lol!) And maybe a self haircut....
