Nocturnal symptoms may include the following:

  • Snoring, usually loud, habitual, and bothersome to others

  • Witnessed apneas, which often interrupt the snoring and end with a snort

  • Gasping and choking sensations that arouse the patient from sleep, though in a very low proportion relative to the number of apneas they experience

  • Nocturia

  • Insomnia; restless sleep, with patients often experiencing frequent arousals and tossing or turning during the night
