How Do You 'Take' Quiet Time?

Sometimes I wish I were a pre-schooler. Quiet time is a requirement. I run around all day doing, doing, doing. My mind is like one of those tape things at the bottom of the screen on CNN or MSNBC. Constant information running over and over. I try to stop it and sometimes I'm able to for a few minutes. But inevitably, it roars back to life. I stop to pray and usually end up on a mind tangent. Then I realize I was praying. Well, thats rude. I mean, I get so irritated when people are talking to me and then just stop and start rambling about something else to themselves or someone else. Usually, if I get a chance to sit and reflect I end up falling asleep because I'm so freaking tired. I fall asleep praying quite often. Years ago I used to do that purposely because I didn't want to break the 'connection' I felt it gave me to God. Now I do it out of exhaustion.
