I’ve been using a CPAP machine daily for over two years without any professional guidance as I moved from Canada to the US. At first, dropping my AHI from 67 to ~1.7 was a life changer. For instance, I used to fall asleep instantly while sitting in the passenger seat of any vehicle. Unfortunately, now my life is plagued with continuous fatigue and I’m not sure if this is tied to my sleep apnea or depression. Does it sound like I need to book another visit at the sleep clinic or should I look elsewhere?
