Hey Stilton,
I was diagnosed with this condtion several months ago. However I went to see a neurotologist a few weeks ago who diagnosed me with having inner ear damage. Since then I have been given exercises to do which I must say have helped a fair bit. Although I don't think I'll be returning to flying for a few months yet I can see light at the end of the tunnel. I've been suffering for about 10 months so I can understand your frustrations.
I thought I sent you a private message with the Docs details but in case it's not there I'll try again.
Cheers
