I agree with NoIdeaWhatToDo.

Magnesium is crucial for sleep both in getting to sleep and staying asleep so make sure you're getting enough. And be sure and take a good magnesium that is easily absorbably like magnesium citrate which is what Natural Calm is. You need to take calcium and vitamins D3 and K with it as the 4 nutrients work together. Another highly absorbably form of magnesium is magnesium chloride. DON'T take magnesium oxide as it's so poorly absorbed that all it's going to do is give you raging diarrhea.

One thing that I use when I'm a little wound up is to wear my orange CSI type glasses that block blue light. The reason I do this is because it slows my brain down by blocking the blue light so my brain thinks I'm in total darkness.

I also have high cortisol levels late in the day so I take a supplement called Seriphos that helps lower it so I can sleep. A few years ago I had a 24 hour cortisol test that showed this, and helped explain why I could be exhausted all day but not be able to sleep at night.
