1. It is intuitive when starting out to think tighter means less leaks. It seems you are discovering the truth is the opposite. Overtightening a mask can make it leak more and then there is the discomfort factor.
2. You mention your lab AHI while sleeping supine. Have you been evaluated for Positionally-affected Sleep Apnea (PSA)? Which position(s) do you sleep in? PSA means apnea is more severe and pressure requirements may be higher when backsleeping. ResMed says 40% of patients have significant PSA.
3. What climate do you live in? Do you know your bedroom humidity level? A humidity setting of 4 is very high and can be counterproductive for therapy unless you live in a very dry climate. I do not use a humidifier except on the coldest winter days when the central heat has driven the room humidity down to 35% or so.
4. What does your leak data show? A "raw throat" is a symptom of mouthbreathing or leaking pressure from the mouth.
5. What comorbidity that causes fatigue are you referring to?
6. You are going to bed with fear that the process will fail in one way or the other during the night. This is normal when we first begin CPAP. It usually takes some period of successful nights before our confidence in the process is good. Additionally, you are coming from an untreated state where you are exhausted and under great stress from the apnea. As your strength builds and the anxiety subsides, your confidence will also bloom.
Bloom? Sorry, but it is spring and I worked in the yard yesterday.
