Granted, sleep doesn't come easy to me at the best of times
But I am one of these who takes awhile to drop off anyway. You know, review the day in your head, think about what you need to do in the morning, take a good 15 min to find the right position of comfy. Then perhaps wait for the stars to align correctly before sleep ensues.
Anyway.....DH is the exact opposite. In an almost piss taking way. He's just come to bed, pulled the covers over himself and is already flat out. What is this sorcery???
