Brain talk, I use this if I cant sleep and have only a few hours before a busy day or when I had to go to work the next morning. But you can adapt it to any situation in your live. ie.
Brain relax repeat several times.
Brain it is ok to go to sleep now.
Brain we can cope tomorrow
Brain relax everything is fine repeat several times.
Brain relax all my body
Brain produce all the chemicals for peacefull restfull sleep.
Brain thank you goodnight.
This worked for my every time, you can adapt it for any situation in your life.
Make friends with your brain, when Brain and mind team up you will be in control.
Hope this helps you.
Just one thing you have to put the effort in, and do it.
