Taking a few minutes before you go to sleep to meditate can help you get into a more peaceful state and thus promote a better night's rest. Let this meditation help you release the past and anything that's worrying you about the future. Really embrace the fact that your time to sleep is one time of the day when there are no expectations of you. This is your time to let go and be at peace.
