Thanks for the additional thoughts!! Yes, my primary care physician has been very thorough in the vitamin checks....in fact I did have Vitamin D deficiency, but use a high quality supplement and my levels are good now. I tend to do a pretty good job with diet, and in fact she talked about increasing my protein at the time which I have done.

Regarding the in-lab sleep test, my insurance is the main problem. They have specific criteria for which they allow the complete sleep test. If I show a month or two of no improvement with the "nasal hygeine" measures, then I'll likely qualify for the lab test.
