I've started doing this too, or at least something closer.  It started  
when I realised how crazy it is that when the clocks change, we all  
start getting up at hour later (or earlier, depending on the season).   
So now I try to sleep about 10-11pm to 6-7am.  I still don't sleep the  
whole night through, I don't think I ever will.  But I don't need an  
alarm any more, and I'm not worried about getting enough sleep.  When  
I worked in full-time, permanent employment, my biggest cause of lost  
sleep was worrying about not getting enough sleep...

I've also noticed that I start to get tired not long after it goes  
dark, but that artificial lighting switches me into some sort of  
adrenaline-fuelled state where I just ignore it.  That can't be  
healthy...

I'll have to see what happens as the winter gets darker, I can't spend  
all my hours out of work in bed...
