Having night time driving as a profession (I'm a security guard, patrolling all
night), I can tell you that there is no other thing to do than take a nap. 5-30
minutes is plenty! I have experienced almost falling asleep 20 times in 20
minutes, I can remember being at a customer's office building, but was too tired
to remember I was driving the 25 kms to get there. It is very dangerous, and I
am truly scared of myself, that I cant control it. It just shows what demand it
puts on one's body.

And when you're 5 or more hours past normal bedtime and truly exhausted, coffee
does not work for me. Neither does fresh air, concentrating, high music etc.
Just sleep.

Drive safely!
