Melatonin is great to help get you sleeping. Valerian root is where it’s at to help you sleep deeper. I still contend that the best medicine is exercise. When I don’t exercise at least 1 hour a day, I feel restless when I go to bed. If I put in at least an hour at the gym or outside, I’m asleep before I know it.
I’m not sure how they could say that children are so exhausted that they can’t sleep. That doesn’t make sense. You’re either physically exhausted or your not.
One thing that happens to me is, I can become mentally tired - exhausted, really - after pulling hours on researching a problem or a grueling day in the cube farm.
I’ve actually used valerian as a cure for migraines - it tastes horrible, but the results are good.
Ditto on the exercise.
Consider yourself lucky. I’ve often experienced insomnia when I’m totally exhausted, but the natural sleep cycle won’t initiate.
