Melatonin that doesn't make you hungry?

Is there a dose of Melatonin or blend of it with other supplements/herbs that doesn't make you hungry? Does timing matter? I'm one of those people that has yet to find a form of Melatonin that doesn't cause nocturnal hunger.

I can't take Valerian regularly because of nightmares and hallucinations. I can sometimes drink it in tea but not every week.
