The melatonin signal forms part of the system that regulates the sleep-wake cycle by chemically causing drowsiness and lowering the body temperature, but it is the central nervous system, so I guess if melatonin works for you that could be good. I have here 5-HTP supplement also known as 5-hydroxy tryptophan, it helps to improve sleep problems like insomnia.
Yes, it absolutely should help you sleep. Take it half an hour to an hour before bed. Also try drinking a cup of chamomile tea before going to bed.

Melatonin certainly helps some people but not others. You take it about an hour before bedtime.
Being unable to switch off at bedtime is a very common problem.
Common sleep aids include warm milk, Chamomile tea, 5-HTP, Melatonin and Valerian.
If you are having trouble switching off at bedtime some light exercise at bedtime often helps you to relax, unwind and switch off and that often improves your sleep. Strenuous exercise at bedtime is likely to ruin your sleep.
