I have no trouble falling asleep, i just always seem to wake up after about 4 hours then my mind starts racing. After i've got it to calm down, i can usually sleep for a further 5 or 6 hours.

Roman: Our bedroom window faces east so we have a blackout blind to keep the early morning sun out. It doesn't seem like anything external is waking me up at this time.. Sometimes it's slightly earlier, sometimes later.
