Watch out for electro-smog, wifi, smart meters, cell towers, etc. Find out if your electrical box is on the other side of your bedroom wall for instance.I unplug every single thing from all outlets, except refrigerator or heater, and sleep some distance from those things. That makes a huge difference to me. In fact, I now always sleep in the back of my truck rather than a motel - so I can get to sleep. Also, you can take melantonin supplements if your room is not dark at night. Most of us need iodine anyway, what with all the radiation. And magnesium. I do even though I eat a lot of greens, nuts and seaweed. It also helps to spray lavender on your pillow and rub it on the bottoms of your feet. Also, you could quit caffeine completely. If you can't meditate, try deep breathing and self-massage.
