Oh that's bad luck she-ele. Azureline sometimes posts about some sort of weighted blanket that is supposed to be good for restless leg I think.
Well, I'm a little sleep deprived too, Baz the Wonder Dog, who is normally the worst watchdog in the world took it upon himself to start barking and growling at 2am.
I lay there for a bit ignoring him, then thought I'd better check.Perhaps the house was on fire, perhaps there was an intruder?
Checked all the doors, checked all the rooms (freaking myself out while I did it mind you, WTH would I have done if there had been someone there?? offer them a cuppa?), turned the outside lights on. Nothing there that I could see.
By then I was very cold and it took me ages to go back to sleep.
