Why should you make a to do list before you go to sleep?  It is a way of training your brain . Guest Elizabeth Louis, says when you do that you're getting it into you unconscious brain so you wake up the next morning knowing exactly what you need to do and where you need to go.  You start the day in the flow. 

Typically when you're when you're not able to sleep at night it is because you're struggling with the fear of the unknown. If you make a list of  three to five you need to do the next day, you will sleep better and you will start the off right.
