Interesting. I for one, can NOT sleep during day light hours unless I am VERY tired. If I have a day off I will sometimes sleep solid to about 12:00 mid-day, but I can never fall asleep once I'm awake during the day. I don't think I would find enough things do to with all that free time, especially in the early mornings. No-one else would be awake, you would have to make friends with an American, and no-one wants to do that, so you can phone him up and chat in the early hours of the morn. Try sleeping pills? Or just get into a night time routine before you go to bed. Not being able to sleep is just one big mind-fu**.
