Do I have OSA? How the heck would I know? I do know as a cargo pilot flying a schedule that is from 10pm until 5am most nights is hard. If you come back from an International trip, it can take a day or two to get back in cycle with your sleep schedule. So what is rested? I know I sleep better at home than on the road, unless I have company. That's a joke. There are times of the day when I get tired, usually around 5pm my time. and that's circadian rhythm, a natural cycle when your body gets sleepy. But to try to impose a sleep apnea restriction and a sleep study is total BS.
My guess is that the next study, test, will be against the super skinny triathlon guys. I hope no one has a low heart beat or low blood pressure, you may be susceptible to scrutiny.
