Percy big hugs to you.
I know what it's like to have carpel tunnel syndrome i had it so bad when i was pg with Alexander but not had it with this pregnancy. Maybe for me it was a boy thing.
The sleep thing is awful i hate trying to roll over at night it takes so much out of you.
Try and get some rest during the day. Sometimes i fall asleep on the sofa and listen out for Kimberley and Alex i get the stage that i can't stay awake any longer and will clean up what mess they make when i wake up.

GL with the rest of your pregnancy.
