I’m not a CPA, but, there was a time I worked the 4pm to midnight shift followed by 75 minute commute home, and still had to be awake by 6:30 for carpool duties. I lived on my 5 hours sleep, normal meals, a cup of coffee in the morning and one in the afternnon and at least a 45 minute catnap on the commute in each direction. After 2 weeks or so, my body became accustomed to the routine.
