Thansk for the replies ladies.
I hope it does go away!
I am now worried about falling asleep in the hospital, OMG how embarassing that's gonna be!
It's funny how I am experiencing insomnia (waking to pee and then not being able to get back to sleep) but when I go to sleep it's sooooo deep!
Apparently DH tried to stir me last night, I didn't even know he'd left till I woke to go to the loo and he wasn't there!
