The most common<unk>  symptom is excessive sleepiness, which results from constant sleep interruption. People with<unk>  due to airflow obstruction often have loud, heavy snoring that is interrupted with choking sounds or loud snorts followed by periods of silence, because not enough air can flow into the lungs through the mouth and nose. The periods of silence can last 20 seconds or longer and can happen many times each hour, resulting in poor sleep and reduced levels of oxygen in the blood. Other symptoms of<unk>  may include depression, forgetfulness, mood or behaviour changes, trouble concentrating, loss of energy, nervousness, and morning headaches. Not all people with<unk>  experience all of these symptoms and not everyone who has these symptoms has<unk> .
