Hi I'm new to the forum. People with sleep apnea can really benefit from allergy shots to clear up sinus and throat congestion. Also seeing a snore and sinus doctor can help too. I have suffered with sleep apnea since I was a teen. I have helped myself find answers more than sleep studies and sleep specialist have. After many ENT's etc I went to a Snore and Sinus doctor who was the first to take a CT scan of my sinus cavity. He reported to my that I had a deviated septum and very large turbinates along with a thick toung and very narrow throat due to large tonsils. Therefore my CPAP was not helping me even at a high pressure, no where for the air to go 😔 I had my deviated septum fixed and turbinates removed. Now my passages way is wide open. What helps me with my mouth dropping at night while sleeping is breathable tape 😊 Placing it over closed lips provents dry mouth/throat which caused me to cough all night. Also eliminate "chipmunk" cheeks☺️ and leaks. I started with a full mask, now I can use a nose mask since I don't need air pressure in my mouth. I have no leaks and it much more comfortable, feels like a have nothing on my face. 1: allergy shots if you suffer from congestion. 2: CT scan of sinuses to check for blockages. 3: Breathable Tape. 4: Test different mask. (I went through 4 types to find the best for me) Hope this helps. Sincerely.
