Continuous Positive Airflow Pressure Machine. You wear one of these Bane-lookin masks: And it opens up the airways that are partially closed when you have Sleep Apnea - when they're closed, they make you snore and wake up every couple of seconds. It's uncomfortable at first, and you go to bed looking like Frankenstein's Monster, but you wake up feeling like a God, if you've never had a good night's sleep before.
How did you become aware you needed to be diagnosed?
Had difficulty paying attention in class or focusing on anything at all. Things that I found enjoyable I couldn't spend more than 10 minutes on without switching to something else. I was fidgeting like crazy all the time. I also started snoring like crazy. Went to my doc, thought I had ADHD, got me a sleep study at the Children's Hospital, and the rest is history! I lost weight wearing this thing. It's not a miracle-worker, but man it's awesome.
