Answer: Bill has it on the head there is no other way than to have someone else observe you while you sleep, and simply write down or tape record the observations!No one can self diagnoise this other than he is not feeling up to par. This can be caused by other medical conditions also such as a twitching leg keeping you from true sleep!I lived for 59 years without treatment!I am now 61 and I swear I feel 40.Sleep apnea simply means stopping breathing more than so many times, for a specific length of time, during a given period of time.If you have apnes then you go to sleep but never really go into what is called REM sleep where your brain really gets its rest! For probably the past 40+ years I really was not truly sleeping! I denied that I had a problem, I really wasn't that tired. But, my wife finally convinced me. This is where an OBSERVER COULD SAVE YOUR LIFE ! (SOMEONE TO OBSERVE YOU AND RECORD YOUR SLEEP, NOTE SOUNDS UNUSUAL BREATHING CESSATION OF BREATHING NUMBER OF TIMES AND LENGTH THIS SHOULD BE GIVEN TO YOUR DOCTOR FOR EVALUATION AND POSSIBLE PRESCRIPTION ) She deserves a gold Star, Probably a Congressional Medal of Honor! I am a Hard Headed 61 year-old. She no doubt has saved my life and no words will ever be able to thank her enough. After all I WAS ASLEEP. ALL WAS OK AS FAR AS I WAS CONCERNED!!! How do I know what quality sleep I encounter, when I am asleep!
