I suffered mania for 9 months in 2011. I was working 80+ hours a week, sleeping 2-3 hours only between shifts. Though physically exhausted, mentally I felt sharp as a tack and super happy. My huge paychecks were spent frivolous while my rent wasn't paid. I kept missing Pdoc appointments and when I finally saw her and got taken down, I felt like my world ended. Lost my job and have had a hard time keeping one since. Let your Pdoc know what's going on, in my experience, the longer your up, the worse you go down.
