...I have complained of dry mouth and dry eyes, and I have fatigue and GI issues as some of my major symptoms...
To tell you the honest truth -- I think the dry eyes is from the eye surgery and you should use Tears Naturale II or GenTeal eye drops (OTC). I think the dry mouth is simply because you can't breathe thru your nose at night...try using Biotene products, esp. mouthwash. (Also OTC). You might consider trying these for a couple of weeks before spending more on lab tests.
I would recommend looking further into your GI issues -- often the common things (Crohns, Irritable Bowel, Colitis, Celiac Disease, etc) have fatigue as a symptom. Although you haven't described your GI issues, I would follow that route as far as I could before worrying about
Just me, just my opinion,
