I'm sorry to hear about your sleep problems. If there is one thing I've never had a problem with, it's sleep. Because I work a tiring day job, and then have all of 2 hours before working an overly-active night job (promoting, natch) I often find myself running through the day fueled by Red Bulls and Iced Quad Venti Soy Caramel Macchiatos.
Once my body goes horizontal, it greedily grabs at whatever few hours of rest it can muster before having to get up and do it all over again. On weekends I'll often sleep straight through to the afternoon. I snooze on the subway to and from work. I am putting in significant time and practice to learn how to sleep standing up like a horse.
But it wasn't always this way. Once upon a time, when Justin was but a wee lad, his overbearing parents thought it wise to force him to bed at 8PM. This was in elementary school. I had a set bedtime and would be sent there against my wishes. Of course I was always a nocturnal creature, before I had the chance to actually exercise that lifestyle. And so I would lie awake in bed from 8PM til past midnight.
I tried everything to fall asleep. I had a subliminal cassette called "sleep like a baby" which was filled with waves, music, and apparently some dude whispering "GO TO FUCKING SLEEP." Of course the problem was that it was a cassette. And so when the side ended, I would have to get up from bed and flip the tape. I gave that up and moved to listening to the classical radio station. But for some reason, I mentally programmed myself to get sleepy when I heard the tone they played at midnight, just after an orchestral flourish, and just before they read the headlines and op-ed page subjects from the next morning's New York Times.
Luckily now that I'm all growns-ed up, I can live my life as I please. This includes staying up to ridiculously late hours. When I'm out, I don't get home until 3am or later. Even on my two nights in a week, I often don't retire until about 1:30 AM. I just do better at night. I'm more alive. And the exhaustion I experience from tablespoons of sleep ensures that, again, when my head hits the pillow, I am out until something loud and obnoxious stirs me.
