The Dreamwear mask is working fine and I don't think I've got any leaks. The idea of the C shaped travel pillow is interesting and I'd love some more information. Do you wear it as normal or reversed? Could I wear it normally in place of my current pillows? Will this make mask leaks even less likely?
BTW had another full night of CPAP and I think it's starting to work. I can't be fully sure as I've got a virus at the moment which is obviously going to leave some feelings of fatigue.
I put the travel pillow on normally, then pull one end under my chin. I use a contoured foam pillow--I usually sleep mostly on the pillow with the travel pillow on it--kind of drop my head into the "valley" be the higher front and rear of the contour pillow. Sounds weird but is pretty comfortable. I need to keep my chin up--I can have awake apnea if I lie on my back and drop my chin, then breath deeply through my nose--blocks the exhale. At the moment I'm having a terrible time with the DreamWear leaking--i just started with a new cushion and I almost think it is defective. It always leaks in the same place.
I use a Philips Respironics chin strap underneath my Dreamwear, and have good success with using both. Not a huge fan of full face masks, or nasal pillows.
