Jet Lag?

I think I am living a myth that states jet lag is worst going West-to-East than East-to-West. I barely slept on the plane being unable to get my long legs into any sort of comfortable position. Sleeping on planes was so much easier when I was younger. I fought to stay up until 10PM last night and though I fell asleep as soon as my head hit the pillow last night I was fully awake at 4AM again which was evening in Japan. Stupid body. I have some fairly routine things to do today that I am looking forward to for the simple reason that I will be able to read everything freely and converse without stopping to think if this is what I really mean.
