Has anyone who has experienced MDD after a cruise noticed if its worse after a long flight? I've had this after every cruise, usually for about a week. Mostly vertigo. The one time I had a short flight (~2.5 hours) it lasted for 2 weeks, but it was also a very turbulent flight. I'm going on a 10 day European cruise with a 9 hour flight. I'm a little worried that the extended flight might make it worse when I return. (we're not staying any extra days, flying the same days of the cruise). On this cruise we only have 2 full days at sea, once in the beginning and once near the end. I'm hoping that will help as well.
