Since my jaw surgery was over 9 years ago, I'm working on a little retrospective post. It's not ready to post yet, but I've written a bit about it in draft form. Basically it's kind of like a "what I wish I had known/done" type post.
Because YES, I would definitely change some things if I had to do it over again!
So look for a new post soonish, which I hope will be helpful/informational.
