Sleep clinic. Part 2.

The second in an eight-part series following the stories of people with various sleep disorders as they visit Papworth Sleep Clinic. This part features Alex, whose night terrors have led to him jumping out of windows, and David who's disturbing night time behaviour is destroying his marriage. In both cases we see their sleep assessed at Papworth Clinic as the experts try to help them. Alex is diagnosed as having nocturnal epilepsy and he is referred to a neurologist. David has REM behaviour disorder and is offered a drug treatment.
