What led to you making so many changes to your normal routine all at once?
After I had been diagnosed with sleep apnea, I received a prescription for an APAP machine (auto-adjusting pressure, in contrast to constant-pressure CPAP). Unfortunately, I still wake up every night after ~3 hours of sleep with a feeling of suffocating and panicking which makes me take off the breathing mask. Therefore I have yet to experience any positive effects from using the APAP machine to treat the apnea.
Any advice from somebody who has gone through the same thing?
