I'm in a similar boat. I go to lay down around 9:30 every night but I don't actually ge to sleep until around 2 a.m.

I just try to relax and stay in a calm mood. My alarm goes off at 6:00 but I hit snooze until about 6:45.... So, I'm getting about 4-5 hours a night right now.....
My sleep aid isn't going to bed until around 5 a.m. and that's part of the problem. (My husband's presance in a room helps me sleep, but he moved his desk out of our room again because he thought I wasn't sleeping.... he doesn't believe that it's worse when he's not there at all....)

I keep trying to overcome it, but before I met him I used to sleep on this same pattern I have right now, or less sometimes. I don't know what the heck it is about him that makes me sleep.
