The One Show's Michael Mosley meets Delia, who despite getting seven hours sleep a night, is constantly tired. During the day she falls asleep whilst talking to friends, travelling and even eating.

Delia has discovered that she is one of the 100,000's of people in the UK suffering from obstructive sleep apnoea (OSA). It meant that Delia was stopping breathing and starting again, roughly 60 times per hour - and not sleeping for more than a minute at a time.
