Idiopathic hypersomnia: When 40 winks turns into 48 hours of sleep

Lucy Taylor lives with idiopathic hypersomnia, a rare condition that makes her excessively sleepy.

The 42-year-old from Newport can only be woken with great difficulty - she needs multiple loud alarm clocks, medication and her family to rouse her.

She said the longest she has ever slept is from Friday teatime to Sunday afternoon - but she describes her condition as "almost torture".
