If the airline/airport has dvd players for rent, rent one with your favorite movie. I did it and it put me to sleep almost the whole way to Heathrow. As for the return trip, knock your wife down, breaking her arm, spend 24 hours pushing 4 suicases thru several train stations and airports, the stay awake while she sleeps so the airport cops don't take you bags. Once you hit the seat, you wil be dead until you land. Worked for me.
