Ned - welcome to Apnea Board!
You mentioned that you don't snore; just wondering if you're sure of that? (does your partner say that you don't snore, or do you just 'think' you don't snore).
I didn't think I snored that much either (my wife is a very sound sleeper). But when I visit my parents and/or inlaws, they notice that I snore very heavily. (without CPAP).
Are you tired late in the afternoon? Do you lack energy during the day?
You may want to read the Sleep Apnea info on our home page at:
