Early to rise, early to fall back asleep

Trying to get up at 5 a.m. is not exactly easy when I cam barely manage to get to sleep before 3 in the morning. Wen I can do so I can get things done in the wee hours of the morning. It works great when I can get to sleep early enough that I can wake up that early, but man, it's a killer when I can not get to sleep early enough in the night. This morning I got up early, but it was less than an hour before I fell asleep in my chair.
