Diane, are you thinking of it for when you fly home from MC? Surely you won't need it on the cruise, you are only losing an hour a night. For flights, I find doesn't matter to me what direction, it is time of day I am flying. Daytime, I'm fine, but crash when I get home after a long one. For an overnight flight, it's hard to fall asleep on a plane, and that's when I find sleep aids help.
