I was wondering as well if you can have mood changes within an episode. I perceived myself as mostly depressed for about four years when I was living with my ex-boyfriend.
But I read in my diaries that I also had times of enthusiam (a few days at a time).

Now I suppose that I have been hypo for about a year due to the sleep I get, the ideas I have and the risks I took (twice in a row debts that took me about three months to pay off, hypersexuality, drugs and stuff).

But I had times in between, one to two weeks, where I perceived myself as depressed or mixed. Always got back to hypo though. I was wondering if I was rapid cycling, but hypomania goes through all of this time like a red string (as we say in German).

Another question I have would be if you still have usual mood swings being in an episode, like being mostly hypomanic but anyway feeling sad for about one hour in one day and then returning to totally hypo?
