I used melatonin a few times, awhile back. It
knocked me out fast !! Slept through the night. The only thing, I disliked about it was, when I woke up, I felt super groggy, rather then refreshed, but after an hour or two felt fine.
Melatonin will not help anxiety. But Chamomile tea does, distributed by Celestial seasoning. It's natural. Really helps a person relax, and also helps with sleep as well, they have different types.
