It's a leap of faith you took Chris, that leap is difficult for many to take.
For me it's not so much a "leap of faith" question as simply a logistical and cognitive one.
Cognitive in the sense that I tend not to make rash decisions, especially medical ones, and thus would rather spend more time researching, observing / talking with other MSers who have already undergone the procedure, gathering information, asking questions, etc. than rush into any sort of treatment (HiCy or otherwise).
Logistical in the sense that I have a number of personal and professional goals that are important to me and that, quite frankly, do come first, especially now that I am so close to accomplishing them. I know that there are risks involved in any aggressive protocol and, even if everything were to go perfectly smoothly, I'd still probably be out of commission (unable to really work, etc.) for at least a few months. So if I choose Hicy I really need to time it in a strategic way, so as to avoid messing up my career trajectory, etc.
