Easy Stroppalot - wonder how you got your name?
Nowhere in my post was there anything intended as a personal insult - it was merely meant as an explanation for why some would hesitate before answering questions such as yours on this forum. I have high regard for only a few journalists (you may have gathered) - hence my initial cynicism (and apology if I had got it wrong).
Your subsequent responses were flippant and sarcastic to say the least 'Yeah, whatever..' and 'stop being so blinking paranoid' - My 2nd post was to explain why those who had been cynical in the first place held those views.
My assumption that you had done little lurking was based only on the fact that I know that similar queries, with answers to all your Qs, have been posted on these pages in recently history - certainly in the last 2 years. I apologise for this, your PPRuNing credentials are safe!
As for an answer - try David Beatys Book 'The Naked Pilot' - lots in there about Fatigue/Tiredness and some examples such as those you seek. Personally, I have taken it in turns to take naps on long night charters - with the express pre-brief that should the awake pilot feel even slightly droopy, he wake the sleeper without hesitation, and if we are both having trouble staying awake we put the lights on and get one of the cabin crew in for conversation. Never had a problem with it.
Sorry I rattled your cage, but as me old pappy used to say: it's better to be a pessimist than an optimist - you are always less frequently disappointed.
