OSA (obstructive sleep apnea) is a lot more common that most people realize. You don't have to snore to have OSA. The stats are that more than 50% of American men have it and don't realize it. If you have a 16" or larger neck size chances are 80% you have it. If you are more than 30 pounds overweight, you probably have it. If you have OSA the treatment is really pretty simple. CPAP. I've been on it for 3 years and have never felt better. I sleep 7-8 hour now without ever waking up, don't ever wake up now during the night and don't get sleepy in the afternoons anymore, I've lost 40 pounds and my BP is way down from what it was 3 years ago (it was never high, but it's low now)
The things that OSA does to your body are terrible and will cause you to die much sooner than you might if you were being treated. Brain cell death, HBP, Heart arrhythmia, GERD, eyesight problems, the list is long and systemic. If you have central sleep apnea, that's a bit harder to deal with, but can be treated effectively with BIPAP.
CPAP is easy to use, not bothersome and 90% of people comply without issue. The big thing is finding a mask that works for the person. Using something like a Swift nasal pillow device makes it a lot easier.
My machine and mask are silent...no hissing, no mechanical noises, nothing...the newer stuff is very good. I download my data from the machine and self treat now. No need to go back to the doc. The APAP machines make it a lot easier as they automatically adjust the pressure needed to keep your AHI down under 5 (5 episodes per sleep cycle of 4 hours) They measure and record lots of data and it's all there to review so you can see how you're doing.http://www.cpaptalk.com
