Of course, you'll be awake around 4AM PPT-time on arrival, so no matter how much and when you sleep you'll still crash after lunchtime on the day of arrival. Of course, there're few better places in the world for an afternoon nap than French Polynesia. After a few afternoon ZZZ's, you should be about on local time.
it also depends how long you are staying in PPif you are planning on staying more than 2 weeks i must agree with Angosturas method
if less it would be better to go to bed early and wake up early
P.S what is your return Flight
