TY for the replies, Jump.
Yeah, I have read that there are three different types of apnea, but hadn't really seen anything specific in regards to exhaling, though I suspected it mattered not either way, inhale or exhale. I have suffered with this for probably 15 years now, but never put a label on it. I have for most of my life experienced a significant sinus drainage problem as well, and I guess I attributed my choking to this until just recently.
What brought me to realizing I might have sleep apnea was a late night infomercial I saw recently for an apparatus that aided in snoring, much like a teeth guard, not that I would buy into anything of the sort, but something within the infomercial did get me to thinking I might have a form of apnea.
I guess I will start the process of finding out for certain tomorrow when I see my GP
