I think I have some kind of sleep disorder. I had Apnea (AHI 26) and had MMA surgery two years ago that lowered AHI to 10. According to ZEO data, I have numerous stage shifts per night, 30 or more with many stages in the 5-10 minute range. There doesn't seem to be an pattern to my sleep stages, randomly in and out of REM, deep, light, etc. An in hospital sleep study indicated 126 stage shifts in 6 hours (post surgery). A 45 minute stage is very long for me. My ZQ is at the high end of the range for my age but I feel treable all the time. Are the numerous stage shifts a problem? Any ideas what’s wrong or how to pursue a remedy?
