What was going on?

I guess I’m lucky, being only a year from when I started observing symptoms (not getting my 8 hours sleep) and being diagnosed with mild OSA.

Beside the muscles of my tongue and soft pallet weakening, what else was going on prior to me becoming aware of a problem? Could my BP have been affected? if so, how (since I was sleeping fine... wait a second, I may not have been aware I wasn't sleeping fine, so that answers the question... whatever could have been caused by a disturbed sleep architecture could have been going on and I wouldn't have know it until the disturbance was strong enough to cause me to complain. Never mind, I think I've answered the question. Is my logic correct?- Mike
