I've been an insomniac since childhood, as well as being naturally nocturnal, so my sleep pattern is all over the shop! I live alone, apart from my pooch, and have a chronic health condition, neither of which help my sleep (my dog is elderly and is becoming incontinent so he needs to be let out every 3 hours or so throughout the day and night or he'll have an accident. And my health condition has interfered with my sleep for years). So I don't have a set bedtime or wake up time. Last night I was settled by 1am, the night before it was 3.30am, and some nights I'm still awake at 7 or 8 in the morning! I would have loved to have had a "normal" sleep pattern all my life but it was never to be (I often used to sit up all night reading when I was a young teen, then go and do a full day at school with no problem at all, before dozing off on the bus home, preparing to do it all again....)
