I need around 6 or 7 hours sleep a night, last night I was asleep by 9.30 which admittedly is a bit early for me, lo and behold I was wide awake at 4.15. I finally gave up and got up at 5.30. I'm working today so I know I'll be tired early tonight which means I'll be awake early again tomorrow. DH can sleep for 10+ hours a night if he's not working. I need to break the cycle of waking so early but find it difficult to stay awake late on an evening.
