I was diagnosed with sleep apnea 5 years ago. I had another sleep test 2 years later that showed the apnea had worsen. I've had trouble with CPAP compliance (mask would be on floor when I woke up) so I have done nothing for the past year. I suffered from insomnia during this time but no daytime sleepiness. Now I've had extreme daytime sleepiness with headaches for the last 5 months. So I had a sleep test in June, but it showed no apnea events! It did say I had no REM sleep. So, can sleep apnea just disappear? My understanding was that sleep apnea was progressive. (I have stayed relatively the same weight during this time.) The last test was done at a different facility. Could the test be wrong? Did I just not have apnea events that night or is my apnea gone and now I have some other problem? (All tests were split studies.) I'd appreciate any ideas or advice. Thanks.
