It works!!

Takes into account your flight schedule and by basically managing your coffee intake, light exposure and time to bed from a few days before it allows you to smoothly transition into your new time schedule. Proven with a time shift of 8 hours (Amsterdam > Colombia) and with a time shift of 12 hours (Colombia > China) this is the maximum time shift someone can experience in earth. It's an inversion!! And i was only one night asleep.
