I'm 35 and I got tested for sleep apnea in the fall and I was having OVER 50 EVENTS PER HOUR.
Got my cpap and holy shit the difference. I am actually rested when I go to bed at a reasonable time. I no longer need daily 2-4 hour naps just to function.
And I also suspect that it might be helping me not get as many colds, because that nightly airflow clears things out.
I'm really glad I have my cpap now and everything is better, but also wish I had got tested earlier, because maybe if I'd caught this sooner I wouldn't have developed some of the other health issues I deal with. But I thought I was so tired all the time because I'm a parent and autistic.
So yeah, even if you think you know why you're always tired, get tested just in case.
