I finally came to a realization about at least a good part of the reason I have such a problem going to bed on time.
Despite the fact that I go to work and spend time away from the kids, while I am at work I am running around like a crazy woman trying to get things done. When I am at home I am with the kids and running around like a crazy woman trying to take care of children and get things done.
The evenings are my only real time that things might be quiet. Usually I try to get whatever chores done and I then can have maybe some quiet time. However I also don't necessarily want the last thing I do during the day to be that I have cleaned the kitchen (or whatever the chore happens to be). I don't mind ending with the feeling I have accomplished a job but somehow doing the kitchen over and over and over again is not the same as say...I unpacked a box, or I sorted out all of my clothes to be donated, or I did something creative.
So therefore I find myself doing little stupid things and staying up really late. It probably doesn't hurt that pre-children my natural preference was for late night (not late late night...just late night....)
So now that I have come to realization that I am fighting my natural preference, craving some quiet time, and generally looking to end the day on something more meaningful or fun...I have to figure out how I am going to address this issue.
