I recommend every single person I know to screen themselves for Sleep Apnea -- My doctor estimates 30% of the population has it and most people go their whole lives without ever knowing.
Personally, my CPAP has boosted by daily energy/wakefulness tremendously, I feel at least 40% more energy each morning when I get a perfect CPAP adherence overnight, and I only had a minor/moderate case. If you snore, you probably have it without knowing.
Please get checked and make your life much better!
