I had a rather mild case of sleep apnea, but I use mild lightly because the condition was still a problem for me and my wife.  We both were not getting much sleep.  Luckily the only real change I had to make to stop the sleep apnea was the position in which I sleep.  My whole life I was used to sleeping on my back, this caused my tongue to collapse into my throat when I fell asleep; the restriction of airflow is what caused the snoring.  After learning how to sleep on my side I no longer snore.  I consider myself among the lucky, seeing I didn’t have to go to a doctor and get one of the traditional sleep apnea treatments.
