Some weeks im asleep by 11 some weeks by 2am but I always wake up bang on 8.30, Its always taken me liturally half hr to a hour to fall asleep once I get into bed when I am tired and try to sleep, just the way it is for me I guess but if I go to bed when I'm not tired I can't sleep it's actually impossible. But I always wake up same time dayly regardless.
And also this threads called night owl... Well there's a bloody owl that likes to sit on our chimney pot every winter warming it's self up on the heat from our wood and coal burning stove and it makes a right racket, honest to god the screeches it makes are shockingly loud!
