Under the right circumstances I love the night, computer, headphones, book, stepping outside for tea-coffee-cigarettes. (Allow smoke to drift up to insomniac neighbour Ted!) Quietly sneaking back into bed at 3:00am and flipping through the channels. Not a care in the world. The right circumstances are being off work the next day with nothing important early.
What is really annoying is fighting off sleep and lead weighted eyelids at 8:00pm because it's too early to turn in and later getting a second wind around 10:00pm and looking at the clock at 1:30am! I'll have gone through a few distraction exercises to disrupt the thoughts that have kept me up, but shutting down the brain isn't always easy. I went three nights straight with four hours sleep a week ago.
I think I'd find myself in Ed's position very easily were I to be a house-husband...er I mean work at home.
OT: I once dreamt the alarm clock went off, went into the shower, then into the kitchen fixing a lunch for work and did a drowsy double take at the clock-11:00pm! I'd been asleep half an hour!
If I need to sleep at say 10:00pm I'll get up early 7:00 that morning, even if I don't have to, and stay awake without a nap all day. I'll avoid anything too mentally stimulating after 8:00pm (yeah, bore myself to sleep). Censored activity with a partner helps. I'll watch a half hour TV of something light hearted, comfortable, familiar-a Simpsons episode for the 1000th time works. When zero hour strikes I roll on my stomach with arms over head as it's a slightly less than most comfortable position and acts as a mental distraction. 90% of the time deep relaxation comes fast within 5 minutes to the body/mind, the position becomes instantly uncomfortable, I bring my arms down and am gone for good. Sometimes mentally playing a favourite song with lyrics intact can work. It's a passive unchallenging mental activity. If things don't work out I may rinse and repeat.
Goofy yes but the point is, through trial and error, to find a personal routine and ritual that works.
Good luck Ed! (get up at 7:00 daily?)
