having some nights,with Postal services...sleep becomes to be the prime,and mixing it with else,s everyday life..morning arrivals are,-well you know. I have fallen in sleep in finals,many times,microsleeps to be scared of. weather,smooth,routine and a good pro friends in cockpit have saved me from worse.as i have them,sometimes. so ref,admitting that,i find a very good reason to be against any stretch of duty and flying hours,which seems to be the trend nowadays. we are even now over the human capability in many a ways.
I run a business in my present incarnation with brutal hours and a long drive home. What works for me is a strong cup of coffee just before the drive home.
Seems to offer 30 minutes of solid protection and 30 more minutes of pretty good protection. Naps work well too if you can grab them, but the two in combination is even better.
How you get your coffee fix is up to you but flying near the ground in microsleep mode is foolhardy.
