Good Night Sleep?

is that a statement...what is considered a good night sleep? Some say you're supposed to get 7 to 10 hours...I'm lucky to get 7 and that's with help. What is my problem...I get turn my brain off when it's time for bed (around 10:30pm). I'm thinking way too much about the day about tomorrrow and of course the "what ifs". I know I've blogged about this before. My counselor calls it sleep hyigene but then again I can't always follow the rules. I know I toss and turn in my sleep because the sheets are always messed up when I wake up or my feet get cold in the middle of the night. Then I usually wake up around 5 - 5:30 and stay in bed until 7:00am. I need to get up earlier because I'm getting to work about 5 minutes later then I should. It all comes back to am I getting a good nights sleep. It is sleep but I don't then it's that great.
