I'm with Kiwi Flyer, as I cherish my time aloft - there's never enough time for reading, IMO.
However, back to your problem ...
About 20 years ago I quit smoking. Tried lots of methods. One was the use of self-hypnoses tapes. Probably didn't have the desired effect because I ALWAYS fell asleep using them. They helped me achieve a state of deeeeep relaxation. I imagine these would help lots of folks with problems flying. If you Google "self-hypnosis CDs", you'll find lots of companies - pick an issue to deal with (we all have something).
