I've been considering it for quite a while, recently reminded by 

. If it were a quick and painless process I'd almost certainly do so, but I'm not a big fan of the "spend months doing paperwork and hospital tests, then days or weeks in significant pain" part. I also have 

some philosophical concerns about anesthetics

If anyone points me to a way to avoid doing most of the paperwork myself, and/or statistics that serious pain and complications are unlikely, that'll make YES more likely.
