GET A SLEEP STUDY!! SEE A DOCTOR....specifically a pulmonologist. you do not need to go to a 'sleep lab'. you can get a sleep study done at most hospitals.
you most likely have sleep apnea and need a CPAP to help your breathing during sleep.
lena: SNORING IS NOT A SIGN OF CARDIAC DISEASE.
mactheknife: this person NEEDS a sleep study first. if a person knows that they are having episodes of not breathing during sleep, 'trying something else' is not an option. oxegen deprivation to the brain is obviously not a good thing.
please see a doc, best wishes.
