Have you talk with a doctor? Would you be willing to take a medication that helps you sleep but doesn't give you nightmares ? I sleep with some sort of light on. I take meds to sleep but it sometime gives me nightmares, so I don't want to recommend it. If you decided to try a medication, choose one that isn't habit forming. I have tried lots of things to fall asleep. Tea, a hot bath, soothing music and white noise ( like rain). Try not to eat heavy food before you sleep and avoid caffeine. I hope you get a restful night's sleep soon.
