I know a lady I used to teach with....her husband was diagnosed with it...she finally got him to go in because of his terrible snoring. He also had high blood pressure and was always tired because he never slept well. Anyhow, he started using the machine at night with great results... he was no longer snoring which made wife happy, his high blood pressure disappeared, and he was no longer so tired he couldn't do anything. I know another man who uses the device with the same conclusion. It is good you are getting tested because it can be dangerous to have.
