Have you considered a desensitization program? They are quite effective for numerous phobias since they actually work through the action that provokes the anxiety and then give you methods to cope with or even overcome the anxiety. I am impressed that this has not impacted you during takeoff due to the anxiety associated with anticipating what you are about to feel. IMP(rofessional)O, this is something that you could successfully short circuit with this type of therapy. I would also consider a beta blocker in combination with the therapy. Worth investigating! Hope this helps.
