Start taking Melatonin. It's a natural supplement that your body normally produces itself but taking about 10-15mg each night will help you to get into a better sleep cycle. I've had trouble sleeping my entire life, I'm the king of insomnia lol. I use to take Tylenol PM, Zquill, sleeping pills with diphenydramine, pretty much everything they made I tried. Nothing worked better for me than getting on a routine of taking 15mg of Melatonin.
