My husband was recently diagnosed with Sleep Apnea at a sleep
clinic. He has suffered from severe, almost
debilitating fatigue for many years, never knowing why. He does not snore. It turns out there is a non-snoring type
of Sleep Apnea, and not one doctor (of many, MANY!) ever suggested this as a cause for the fatigue and exhaustion.
Now he is using a CPAP machine, and adjusting quite well!
