There are some great teas that can be helpful to some people. Tension tamer and sleepytime tea both work for me. Not 100% but better than nothing! I also make sure I have a good night time routine, no caffeine during the day and I try to be active during the day so my body is tired enough to sleep. Too little activity and I will sleep, but not well. What makes it so hard for you to fall asleep? Is it thoughts or restlessness or something else?
