I had a sleep study done a few years ago and am seeing my doctor again tomorrow morning to see if I need another one. I was just looking at the previous study agan and have some questions.
The study did not find apnea, however I did have frequent sleep arousals as a result of my breathing -- the doctor called it upper airway resistance syndrome (uars). The mechanism (and treatment) is very similar to apnea except that instead of holding my breath, resulting in lower oxygen levels, when I had trouble breathing I woke myself up -- not long enough for me to notice, fell right back to sleep each time. This happened about 12 times an hour -- every 5 minutes. He told me that while this condition does not have the health consequences that apnea does, since my oxygen levels were stable, it could help explain why I am exhausted all of the time no matter how much I sleep.
He did not, however, talk to me about my sleep architecture, and looking again at the results it looks very off to me. I am wondering if this is because of the arousals or if there may be other things in play that also need attention. I'm especially concerned by the fact that stage 4 isn't even on there, which I'm interpreting to mean I literally did not get any. Note: I am on antidepressant medications, which at least partly explains the long REM latency, but it's really really long! In addition I also take vyvanse for adhd (similar to Ritalin or adderall) -- the max daily dose twice a day (so double the max). I can do that, drink a cup of coffee, and pretty easily still take a nap, which I find very disturbing...
Here are my architecture results:
N1 - 4 min - .8%
N2 - 270 min - 51.3%
N3 - 193.5 min - 36.8%
Rem - 59 min - 11.2%
Time in bed: 570.5 min
Sleep time: 526.5 min
Wake after sleep onset: 24 min
Latency to sleep onset: 20 min
Latency to persist sleep: 30.5 min
Latency to rem: 391 min
Total arousal index: 15.2/ hour sleep time

The scary thing about that is I took the more recent test while unemployed and was sleeping 10-14 hours a day! Sometimes even more. If I can sleep that much and still be sleep deprived I think something must be very wrong.
