Choose a specific bedtime and stick to it.
I have been going to bed way too late...it has something to do with the house finally being quiet, me enjoying my down time, and one of my favorite shows that is on "after dark". With all that being said, my new bedtime is going to be 11:00. That may have to start after schools starts though, now guarantees.
By the way does anyone know why on the East Coast and West Coast it is the 11 o'clock news and everywhere else it is the 10 o'clock news. I much prefer 10 o'clock because then if I want to watch Jay Leno, I am not up past midnight.
