David was 20 years old when he commenced CPAP. He had always been tired. He had really struggled with fatigue during year 12. He had been reassured his fatigue was normal for a teenager. This was incorrect. His fatigue was due to his Obstructive Sleep Apnoea, diagnosed after his GP had requested a Mycroft sleep study. After David commenced his CPAP trial, he felt better. After a few weeks he was able to recommence his law degree.
