Also, you have not indicated your general overall health but I find staying in good physical shape helps me content with the long days of travel with multiple of long flights.

Finally, you are AA/PLT but don't say whether you are an AC member. When I connect through an AA hub if time allows I always take a hot shower. That without a doubt gets the "cobwebs" out of my system.
