I was recently diagnosed with Obstructive Sleep Apnea Syndrome. The question most asked by the doctors was, "Do you feel refreshed in the morning when you wake up". I was referred for a sleep study which resulted in the diagnosis. Its important to understand that a sleep study tests for sleep disorders, not just Apnea. A sleep partner can see if you appear to stop breathing, but that observation is not foolproof. Its possible that breathing stoppages can occur without the gasping for breath usually associated with apnea.
