There was a nice story in Ernest Gann's 'Fate is the Hunter' about a DC-6 Captain with a raging hangover, who was making frequent trips out of the cockpit for paper cups of water. After about the third apperarance, an old lady pax asked him 'what he needed all the water for'. Something snapped and he replied: "Madam, I am attempting to extinguish a cockpit fire." Unfortunately, she wrote to the airline to commend his bravery.
