What are the symptoms of sleep apnea?

If you have sleep apnea, there are times during the night when you stop breathing. However, you may not be aware that you have sleep apnea. It may be your partner or another family member that notices the signs first.

Having sleep apnea can make you feel very drowsy during the day. You may find it hard to concentrate or remember things, feel tired when you wake up, and feel moody.
