You would think that not sleeping for one entire night would maybe cause mania the next day, but I surprisingly perfectly fine after not sleeping. I am getting better but sometimes can be very impatient still, with my family and even my girlfriend.

I have been taking a Zyprexa here and there once in a while as well, if my dad thinks I'm being hard to handle he'll sometimes recommend I take one
