That's time enough to run errands, many of which you should be able to take care of during the night you're staying awake through anyway. Anything else, just get others to pick up the slack. You can't do everything and you don't need to. I know maybe they haven't proved themselves worthy or whatever the heck reason you have for not handing off something as simple as 'get today's food,' but maybe that's because you don't give anyone else a chance.
