Rsmy59,
Yes, I've been through the drill 3 times. It's not really that big of a deal.
I get NO, nada, deep stage sleep - which at my age is not right. Been that way since at least '06, confirmed last Dec. And get this, it's not considered a sleep disorder. I got a CBT referral from my last study.
That said, you should get a study done to rule out OSA, etc., or to treat it if it's there.
If you have something like me (or more commonly alpha-wave intrusion into delta sleep), you'll probably need to look for someone besides a pulmonologist who just isn't trained on sleep meds. And I'm being generous based on the idiots I've seen.
Some docs know their sleep meds but they're just not usually the front-line people you'll meet, you'll probably have to search them out. My best resource has been a psychiatrist who stays current on lots of stuff. He even knows what cytokines are. I always take at least one paper for him to read.
Best wishes,
Otis
