Thinking too much too late!

It is just after midnight where I live and I know I should go to sleep but I just can't turn off my mind. I have so much running through my head, quilts I want to make, quilts I need to make, working on my book, who should I hire to design my website, etc...

I have to learn to let these thoughts go at night so I can sleep. I can't be the only one who deals with this, can I?
