It's a bit like sea sickness ... if you are unlucky enough to be the type to be struck down, only more exposure is the cure. Unfortunately, unlike boats where you can spend hours or days getting used to it (or feeling ill from it
), with flying there is no easy answer! Certainly, expelling any fear of it will help dispell the butterflies of anxiety, but I'm afraid you'd need to be a very rich man to actually do enough to de sensitise yourself.
