Yes melatonin is cheap and if you want the job done quick and be put in a coma then melatonin is your friend. The only thing bad about it is the grogginess you feel the next morning. And may want to sleep again during the day. It does make you feel horny the next day though because it is a hormone. I switched to skullcap, because it doesn't feel like your arising from taking an anesthetic. It brings on more of a subtle relaxation and is suppose to improve nerve, organ function and anxiety which can sometimes cause teeth grinding. I don't know what it is lately maybe it's been the skullcap, and catnip but the last two days I've been getting powerful spontaneous erections that I've had to fight to go away. It could easily be the zinc piconilate and optizinc taking affect, but now the erections are relentless.
