I recently started a new single pilot freight run that flies basically the midnight shift however I was wondering how other pilots on similar schedules actually get enough sleep to not drive themselves insane while having as "normal" of a life as they can.

The Run is a weekday "Out, layover, and back" run where I am home every day in the middle of the day. This means that I actually get my FAA required rest at my home during the middle of the day and not at night. Here's what the schedule is like:

Leg 1: ("Outbound" leg)
Show: 7:30pm
Block Out from home = 8:15pm
Block In at layover city = 9:45pm

Layover:
Hotel = 11pm - 4am

Leg 2: ("Return home" leg)
Show: 4:40am
Block Out: 6:30am
Block In at home = 8:00am

Off Duty:
At my home = 9am - 7pm

I have been trying various combinations of split sleeping (4hrs at layover + 4 hrs at home for example) but I am just not taking to it very well. I have been on the run for a little over a month now. Thanx for your input!
