For reference, I'm 25M, 6'0" 186 lbs., 15-16% BF, with a 17" neck. Not sure what else is useful. I attached a list of symptoms in a document as well. Broadly, I have a moderate sleep apnea diagnosis (15.2 AHI, 17.3), and no insomnia diagnosis. I had an in-lab sleep study last Tuesday night, where I only slept 2.5 hours due to a BiPAP titration after a wakeup, where I couldn't fall back asleep.
Beyond this, I have been utterly confounded by a recent development since March of this year, where my sleep duration has steadily declined from 7 hours and 19 minutes per day to 6 hours and 28 minutes this October. Lately, nights were quite bad, at 4.5-6.5 hours, and the two medications I started last week have seemed to help, albeit with massive drowsiness during the day.
Importantly, nobody seems to know why this is going on. My theory is that since I came back from a shoulder surgery last year and started lifting again, my rapid muscle gain literally demanded too much oxygen for my underlying SDB to handle, so I ended up getting flow limitations and apneas/hypopneas/RERAs that woke me up. I have the best physique of my life, and the worst sleep.
I've tried so much to fix it too, as the document shows. I really don't think switching to BiPAP or ASV really matters all that much, and I don't think MAD is good for me because I have jaw clicking. I really want to avoid jaw surgery, and my palate is a normal width, so expansion isn't indicated. In the meantime, I am having a horrid QOL. My brain is fried, I am getting ED because of the SDB that is killing my chances of relationships, I am so tired all the time, I am damn near anhedonic because of it, and I just have no real desire to do much of anything anymore. Are there any actual, unconventional solutions that I can try that aren't insanely expensive or invasive?
