Travel 10-12 times/year to Manila,,13 hours
The best working for me are 2-3 hours in to flight and after some vine (2 bottles

excuse me! airline Bottles ofcors) i try sleep "all way"! landing 09.00 and never sleep that day until night.( i used to do the mistake sleeping earlier,,then i get this "jet lag" for shore)
And to much drinking together with the time change are making it MUCH worse

, i still have to figure out why in opposite direction i cant get any success,,i am dead for 2 days
