Jetlag

I'd love to find some helpful advice on how to not get steamrollered after travelling for 32 hours. Despite stretching & walks during the flight, staying away from caffeine, eating at normal times, and resting for 2 solid days when i first arrived home ...
sleep evades me. My nights & days are totally backwards.

I have been Gobsmacked. (yawn) it is 6:47 AM & I have been up for 4 1/2 hrs.

Help?
