For example :
Obstructive Sleep Apnea is a very under-diagnosed sleeping disorder which I was diagnosed with in December 1995.   Apnea is not realistically a life or death issue but it is very much about quality of life.  Since my diagnosis I have been getting treatment.  To find out more about the condition, which is most noticeable in those who snore, see the following: Apnea: The Sleep Well.

Sleep Apnea -- IF YOU CAN ANSWER YES TO MORE THAN ONE OF THESE you should tell your doctor to check you out for sleep apnea:
1.    I’m heavy.
2.    My neck size is 17 or over
3.    I fall asleep in inappropriate places
4.    I feel way below par much of the time
5.    Someone who can hear me sleep has noticed that I snore very loudly, then stop breathing and then start breathing again with a gasp.

Snoring
Afternoon Drowsiness/Nodding Off
