Enjoy J, this is how I do it after I get on a long flight:

1. Get a chaimpaign right away
2. Red wine before the meal
3. Another red wine with the meal
4. Port with desert
5. Whisky to finish it off. Flatten the seat and go to sleep
6. Wake up in 4 hours, and repeat 1-5.
7. Where the heck did I put my custom form? Ask the FA to get me another one.
8. Fill out the form with Vodka in hand
9. Arriving at PEK. Just in time for the bed at hotel. Taxi drivers don't even expect tips.

Enjoy :-)
