Hi there
I really sympathise with you on the flying front. I hate flying and I mean hate. I, like you, have an eight hour journey for the honeymoon which I am not looking forward to. Last time we flew, I worked myself up into such a state the night before I was sick.
I think Karen's idea of rescue remedy is a good one. I now get tranquillisers from the doctors for the flight and they just keep me relaxed enough not to worry about it too much.
Good luck with it. You are not alone, so many people I talk to feel the same.
