Fully agree about taking a sleeping pill on overnight flights - it's one reason I love flying from the west coast (SFO) nonstop to Europe. It's a 10 hour flight, so you can get a full night's sleep and arrive waking up in time for their morning. Only problem is getting to sleep soon after a 2pm departure, and that's where the little pill comes in. My doctor and I have an agreement: he prescribes Halcion, and I only use them on overnight flights!
