How do you know for sure if you have OSA vs Hypersomnia? Is that proven by the sleep study? I was diagnosed with OSA but can’t use CPAP or oral appliance so I have had to rely on 2 mg of Lorazepam nightly for many years or I can’t sleep BUT I have to nap 2 hours every afternoon. It seems like such a waste of a life but I can’t function when I hit that fatigue wall!! Any others with something that works for them besides CPAP or oral appliance or Inspire (I won’t try that)?
