I have sleep apnea and have to sleep with that darn machine, but I swear it works.When I was younger and in my college years I used to be a night owl too, sleeping in the day, and staying up all night. I was just about forced, after I got married, to become a day person, which worked out good because my husband is a day person, and if I wanted to spend time with him I would have to be awake during the day!!! I enjoy the sunshine now, before i could have cared less about it, I preferred the moon.i did go through a process of becoming a day person.i had to go through a few days at once to try living in the day.It took about a month, but now I sleep from about 8:00 PM to 6:00AM. One other thing too is I am very medicated as I get seizures and need meds for them. I hope you can work out your sleep problem, the day is great, but I really only like it when the sun is out now too!!
