99% of the time you will not have problems sleeping without the machine. Remember that you are not required to take the test because you are having any symptoms or discomfort. Sleep Apnea is a like silent killer. Every night you sleep and stop breathing for short periods of time does damage to your heart and your brain which leads to heart attack and stroke. Most people that die from sleep apnea do so in their sleep from cardiac arrest or stroke. I'm speaking knowledge of 35 years from inter acting with doctors and nurses and respiratory therapist who treat this condition. Not trying to scare anyone and surely I agree with you to each his/her own. I am just providing some information that may be helpful to anyone who choose to use it. Its totally obvious to me that you have not thoroughly researched the condition of sleep apnea. Good luck to you and may God be with you.
In 2003 my cousin's 41 year old son died in his sleep of an apparent heart attack brought on by sleep apnea. He was fit and not at all over weight. A totally unexpected situation for sure.
