Fair enough. I was in a bit of a foul mood when I answered earlier - my apologies. I want to go to sleep quickly to minimize "wasted" time. I've found that I function best when I average at least 7 hours of sleep, so asleep by 7 would allow me to get up before 6 and feel well. I want to get up before 6, because when I do get up early, I enjoy the quiet time in the morning before the day ramps up (including my young son waking up and requiring attention). Consistency is important mainly because I need/want 7 hours of sleep, and I want to get up before 6 so that I have some time in the morning as previously mentioned. Usually if I'm still awake in bed for a while, I'm thinking. About any of thousands of things...
