So there's been some nights now where even though I'm quite tired, snuggle into a comfy position, breath deeply, close my eyes and yawn... 1or 2 minutes later I feel this insurmountable need to move, anything my legs, arms or switch position and if I don't do it I get this weird tension, like buzzing inside me, and I get increasingly conscious of my body, legs especially, it's mentally uncomforatable and even end up jerking my legs when I try to ignore it. 

This keeps happening until I pass out exhausted around 3am, while reading or smthing. I fucking hate this sensation and it's starting to take a toll on my day.

 Any ideas how to get rid of this?
