I wanted to share with you all a way I find easier to get to sleep with "wiggly legs". I have a heated under blanket for my bed which I put on before I get in so it's all comfy. I lay on my tummy, left arm down by my side, right hand by my face with my feet just over the edge of the bed. I pull my feet into the end of the mattress which really seems to be a non-wiggly way to ease the weirdness/pain. I leave the blanket on until I'm just about to fall asleep and always put a dvd on or read to try and not think about it.
This could just work for me but thought I'd share on the off chance it helps somebody else
Sweet dreams everyone x
