re: What time do you go to bed at night and how many hours of sleep do you get?

I'm 21. I definitely stop breathing in my sleep without the CPAP and sometimes with. I'll have a dream where I'm stuck under water or have something over my face that won't let me breathe and eventually I wake gasping for air. I've tried sleeping 8 hours a day for a week or so and I just can't ever have any energy or mental clarity with that amount of sleep
