Hi all. I've been diagnosed with Severe Obstructive Sleep Apnea for about a year. I did the in-home test first and after they diagnosed me and got me all set up and I was still really tired. They did a sleep study at the doctor's office and found my pressure should be 15 instead of 12. I also have a TAP device because of how far back my jaw would relax at night and the chin strap wasn't cutting it. I first tried a nasal pillow, but that wasn't enough because the air would just blow out my mouth. I've tried several full face masks, but I have a problem with keeping a good seal. I tend to drool and the saliva breaks the seal. I've played around with humidity and heat and tend to either still drool or get really bad dry-mouth. The other problem I have is that when I'm falling asleep and relaxing the air from the CPAP machine, instead of going down my throat, will rush into my mouth and make my cheeks puff out. It doesn't break the seal, but it's very annoying and makes it hard to get to sleep or get back to sleep if I have to adjust my mask. Has anyone had a similar problem to this and how did you handle it?
