Thanks, once again, for all your suggestions. I used to take Vallium, prescribed by the GP every time I flew but it would not make me feel relaxed enought - no matter how much I took - and, believe me, I tried some really high doses! I ended up drinking with it which was the only thing that really helped and then I would be feel lethargic for the next day or so. Now I just stick to the drink!
MB - I am really finding your link about fear of flying useful. It's very long and I'm still ploughing through it but it's very good. There is a chat room also so I'm going to ask about the walkman cassette thing in case I can play that whilst I take off and land. I might also buy the book!
