 I don't have jet lag because I sleep on the new zone. I sleep on the plane. But for those of you for whom it is an issue, and you can get off a prescription if you're taking one, I would try Z-Factor. What can you lose? You invest in one bottle of Z-Factor. Go to relieffactor.com or call 1-800-4-RELIEF. 800, the number 4, and the word RELIEF.
