My ex had restless leg syndrome; when he was awake he had some level of control over his movements but not when he was asleep. Once he was in a deep sleep his legs were very 'jerky' and it used to disturb me to the point I'd go and sleep on the sofa (a couple of times he 'kicked' me hard enough to leave bruising). It was a very lot worse if he'd been drinking so I reckon Chris has been hitting the free bar just as much as Sarah has.
