Hmmmm, this is a difficult one for me since I just got a diagnosis. However, looking back the past 10 years I would say I cycle about every 3 weeks with minor mania for about 2-3 days. Then I have a major depressive episode for about 2 days afterward and then fine. However, every 3-6 months I have a MAJOR mania episode and that is when I'm pretty destructive. I don't know if it's because I've been good so long that I'm like....***** this and go crazy or if my mania just ramps up during that time. Who knows.
