I replaced all stuff on my cpap machine yesterday. I slept at a weird time, but woke up feeling abnormally functional. It is possible that part of what has been wrong with me was some kind of hole in the hose, or mask, or something, that was making the seal malfunction, which was allowing me to choke in my sleep. It actually makes sense because the symptoms of prolonged apnea include extreme anxiety. Combining apnea with the other stressors could explain a lot of my extreme symptoms. If I start feeling better regularly from this point on that will be a pretty clear indicator of what’s been up.
