It all started because of vanity. My CL2 pushed my forehead down and the nasal pillows pushed my nose up into my forehead thereby causing a small wrinkle at the top of the nose near my forehead. I decided to try a light silk eye mask under the forehead piece to see if it would reduce the friction and keep my forehead/nose area skin flat. Not only did it work for that, I had the best night sleep ever! I was astounded!
I've discovered that by wearing an eye mask, I am sleeping deeper and longer. And, what the heck, what's another apparatus strapped on my head? My numbers are consistently 0.x - 1.x versus 0.x - 3.x. I feel so rested. Yeah!
Since finding the eye mask works so well, I bought one that allows space for my eyes versus pressing on them http://www.amazon.com/gp/product/B0015Y754Y. I chose the Escape Luxury Sleep Mask with Earplugs and Travel Pouch - Black because it has the space and because it was large enough to fit under the CL2 forehead piece. The picture below shows looking at the inside of the mask that's next to your eyes.

The only complaint I have is that my face is small and the mask goes down too far under each eye. If anyone is interested I'll post measurements.
I'm astounded how much better I sleep - perhaps this will help you too : )
