I did not put strict detail in the medical interventions as this is not meant to replace medical advise and its not as engaging in story form to list things rigorously
But I did followup home tests after treating it, and have done polysomnography which is the gold standard of diagnostic test. I also wear continuous spo2 monitoring on a monthly basis to see where I am from my own device bought on amazon
To treat, I needed a team of specialists (sleep doctor, allergist, ent, maxillofacial surgeon, GPs, and a gastroenterologist) to tackle the various causes and measure the effect. I also consulted Dr Kasey Li, probably the world's leading expert on sleep apnea surgery. He recommended his own surgery expanding the maxilla, but I don't think I need to go that far as its very expensive and I am much better today. I've seen several sleep doctors, will list Dr Sinha at peninsula as someone I would recommend, along with AXG Sleep Diagnostics for an affordable polysomngraphy if you need to pay out of pocket. For ENT, I will also recommend Dr Gerald Kangelaris (skilled surgeon) in SF and Dr Andrew Murr (head of ucsf ENT) if you need a second opinion
Also a lot of my interventions are done daily. So if I miss things or get lazy I can recognize if there is a difference. I also motion record myself automatically every night. In the morning I review how much I toss and turn. Its been about a year of experimentation
