I just came down off a mild (and brief) hypomanic episode and I slept like a log, 8 hours a night, through it all. You can't always gauge an episode by the amount of sleep you're getting.

You sound hypomanic to me. Sometimes we have breakthrough episodes even when we're well-medicated. A friend of mine who used to be a psych nurse told me once that there is such a thing as a "medicated mania", in which there are manic symptoms that don't quite reach the threshold of a major episode. But then I'm probably not telling you something you don't already know.

Just don't lie to your pdoc when you see her on Monday. If she's a good one, she'll be able to figure out that you're hypo without you saying a word. She may be straitlaced but she's heard it all, you know that.
