I wonder if you had the same kind of acute pulmonary edema that happened to jesvetmed a few years ago? I'm going to PM her and ask her to weigh in on this thread and describe what happened to her. If so, it's truly not something you can argue with, and strength of mind has nothing to do with it---it's a real physiological event.
I am so very sorry you had such a crappy experience but so very glad that you're turning forwards towards the things you love to do!
Chris is looking forward to riding with you next summer at London-Edinburgh-London.
