I agree that the prudent approach would be to get tested for sleep apnea in a sleep lab. The results will probably enlighten and astound you. One caveat, I know of no one who has experienced the sleep lab who has not been diagnosed with sleep apnea. As noted in posts above the medical implications could be severe, predominantly stroke and AFib.
The solution, if indeed sleep apnea, will probably be a Cpap. I have been a long time user of a CPAP, probably over 20 years. Takes a little while to get accustomed to but it is now automatic. There are a number of options for masks and your doctor can experiment which one suits you best. Some individuals can never adapt to use of a CPAP, I suspect for some portion of individuals in this category it is their preconceived notion that they don’t require a CPAP.
Arranging for a sleep study would be the prudent approach. A major benefit would be domestic tranquility.
