You have to get your mind to shut down as well as your body...I know it may sound silly but if you start out by telling your toes to go to sleep, kind of in your head, just toes go to sleep and then pause and tell your feet to go to sleep then your calf and shin, your thigh...and keep working your way up it helps relax you and often times can help you shut down and get to sleep.
