Anyways, all done up (for the left side only so far), it looks like this:

The notch on bottom is for my shoulder. The mask fits in the notch on the left side. The block under the notch keeps my chin from drooping down towards my chest as I sleep, which loosens the bottom straps and causes major leaks. The block on top is a wedge that keeps my forehead from rolling over into the mask cut-out.
Normally, while I'm learning to sleep with the mask on, I'm sleeping very light. The slightest air leak wakes me up. But for 3 1/2 hours, I had no wake-ups -slept like a rock! Unfortunately, the bladder couldn't stay asleep. When I got up, I realized my neck was a bit stiff - I'd been locked into lay on my left side all this time on a very stiff pillow that was much higher than I was used to. So I went back to scrunching my regular pillow until the alarm went off. More comfortable for my neck, but not as good of sleep.
So, I've proven to myself that one of these will help. Now all I gotta do is find one that looks like this and I'm golden!
