My wife has started getting up twenty minutes or so after having settled nicely to sleep at about 10.15. I can get her back into bed and settled, but she then gets up again ten minutes later and eventually refuses to go to bed completely. I've taken to locking the front door, shutting thedoor of the room where I sleep and trying to get a couple of hours rest. Usually something disturbs me around three in the morning and I get her into bed. The house is in chaos with lights on and various items scattered round at random. It's happened three times this last week and I'm literally tired of it!
