The symptoms of sleep apnea could be summed up as not being able to sleep deeply and suffering the consequences of that. A sleep apnea sufferer might snore often or loudly, silently pause breathing while sleeping, wake up in the night choking and gasping, find themselves having to use the washroom at night, and wake up feeling completely dissatisfied with their sleep. During the day they may have headaches, difficulty concentrating, feel irritable, have memory loss or foggy brain and may experience a decline in sexual desire.
