That's certainly one of the first things they checked for, which is understandable.

They started with a home sleep study (you pick up the equipment and are shown how to put it on before bed), but it showed that my breathing was fine, blood oxygen levels were normal, and I snore less than the average person.

So that's when they had me do the full study where you sleep in a lab hooked up to monitors to track breathing, brainwaves, muscle movements, etc.

When my father did his sleep study, they found that for every hour he slept, he only got 15 minutes or less of restful sleep. Sleep apnea is crazy.

My own sleep study, done at age 24, showed that I had (have?) mild to moderate sleep apnea. They recommended I don't drink, lose ten pounds and exercise regularly. No CPAP until it's worse. I chose to suffer poor sleep instead.
