I am also waking up - constantly!! I get up on the hour three seperate times to go to the toilet and then im awake from 3am for about an hour or so! Very annoying! I try to use a relaxation breathing technique that used to work when i had to do really early starts for work (to get me to sleep earlier at night) but this isnt working! and the toilet trips, leg cramps, expanding belly and a dog who insits sleeping right between DH and I isn't helping! hehehe. Oh well... I guess its all preperation!
