EI I used to be a terrible flyer, but through working for an airline, valium and the magic bach rescue remedy I've masterd it.
I highly recommend you buy bach rescue remedy, buy a bottle of mineral water and dilute some of the remedy into it. Then when you hit turbulence just sip at the water. It worked for me. I don't know if it has any real effect or if it's just physcological but it really did help. Now I can sleep onboard which is a major achievement. The only other thing I can suggest is trying to sit opposite a jump seat occasionally and have the crew chat to you about what is happening. I had one chap once on bmi who talked me through take off, turbulence and landing. It really got me on the road to recovery.
