Loud snoring, periods of breathing cessation, abrupt awakenings with shortness of breath, morning headaches, excessive daytime sleepiness, insomnia and irritability can manifest in sleep apnea sufferers. A sleep specialist or doctor should be able to confirm diagnosis, possibly doing a sleep study.
