I now have to work 19 hours today and tomorrow in order to obtain my first 80 hour work week which is easily manageable. I might even be able to clock in at 84 hours. I also feel fresh and up beat. My last string of working each day more than 70% of the time lasted 45 days. Right now, I'm on about day 13 or so, so it should be a while before I need a break again.
