MSLT (multiple sleep latency test) question, I just went to the doc to discuss the results today but I thought of this after I already got home. XP I did not enter REM during any of my naps. Has anyone heard of that being significant? The doc mentioned it and seemed to think it was strange but I was so tired I couldn't really follow a lot of what he was saying. I'll have to ask him to explain again at the next appt but I'm curious if anyone here knows anything.
