Eric - I know exactly what you mean. I have always been a night owl and find it really hard to get to sleep at a decent time. Even if I don't have anything to work on I will just sit reading boards and surfing. I usually end up in bed around 5am even though I know I have to get up at 8AM to get my kid ready for school. I usually drop him off then go back to bed for an hour or two.
Friday night comes and I go to bed knowing the kid doesn't have to go to school in the morning.. woke up at noon today.. AHHHHHHH
