Break the Matrix

I would LOVE to get a mouthguard and try it this way!

For the time being, I've been doing it via face pushing, by putting my thumbs on the palate where my eye teeth are, and pushing upward and outward as shown on the FP website.  I am getting results this way, but I prefer to do the mouth guard thing.  I'm not even sure where to buy those.

I do it with my fingers in short intervals (3 min at a time) a couple of times a day.   I can feel it in my TMD joint and my cheekbones get slightly sore, like right after an NCR session.  In my case I believe less is more.
