Migflanker, I am surprised at your post. With a handle like yours I would have thought the rules were simple, time tested and true. No smoking within 24 hours of flying, no drinking within 100 feet of the aircraft, etc, etc. For me, after forty plus years of banging around the world on planes, helos and boats it is even easier . . . sleep when sleepy, eat when hungry, and keep Dr Absolut at hand for all other times . . .Tesek
