HeartofSpades, if you or anybody else operates a flight that you think is unsafe, and I make no apology for shouting, FILE AN ASR. I had a similar but less extreme case a couple of months back when no fewer than 7 cabin crew came to the flight deck asking if what we were doing was still legal (it was) and complaining about how tired they were. I offered all of them an ASR form and help to fill it in. None of them would.
If you don't look after yourself don't expect anybody else to. Especially in the Middle East.
