Got a CPAP machine and for the first time in years I woke up without a headache

For most of my thirties I assumed everyone wakes up tired. Coffee at 7, coffee at 10, falling asleep in the 3 pm meeting, a headache that lived behind my eyes. I thought it was the job. Turns out I was stopping breathing 40 times an hour. Second night on CPAP I woke up at 6 without the alarm and lay there confused because nothing hurt. I am posting this for the men in their 40s who snore and are told to lose weight and leave it there. Get the sleep study. It was the most useful medical thing I have done in a decade.
