I have never had a full-on mania. It is almost always mixed, which I attribute to taking meds and starting fairly early. However, when I do get mixed I tend to get paranoid and I start to ruminate about everything.

Also oddly enough I've almost never been able to sleep 2-3 hours for a couple days. I have a habit of sleeping 10+ hours a day (sometimes with naps) so I tend to consider 6 or less 'not enough'.

I think my paranoia keeps me from doing anything 'bad'. I'm overly concerned about not getting into legal trouble or trouble with my family that it usually squishes any appeal of doing something outrageous.
