it would also be interesting to have a survey-based picture of what sleep problems occur in ME/CFS. My impression is 'all of them' but the picture must surely be more revealing than that
It's partly the comparison that might be revealing. On the whole, the main complaints of people without ME/CFS seem to be that pain and discomfort keeps them awake, or that they're wrangling with a difficult or scary diagnosis, or that their meds make them sweat, itch, get reflux, or whatever.
People with ME/CFS will give you a dozen or more reasons and none stand out as "I'd sleep so much better if I could only get rid of this". As you say it's everything, and if you tried to boil it down you'd probably end up with two broad categories: PEM, and ME/CFS.
