Mine runs about like a loon all day but I make her go to bed at 7pm. She doesn't sleep straight away mind you, just lays there and listens to story tapes, but at least we get a window of sanity or I'd be pacing up and down all night.
And if she could hang on until 7.30 in the morning I'd be over the moon. Still, being forced to get up at 6am means I get lots of stuff done early...

You may have to move. I know I sound all judgemental and all, but you've seen her and her kid and her brother, and they all follow the same sort of vein. Chances are any man she hooks up with is going to be 'interesting' too. First there'll be noisey sex, then arguments, then things smashing, then him standing outside at 3am yelling, and her throwing things out the window at him.
Then the police will come.
Sorry...flashback...I'm so glad I've moved...
