I’ve found melatonin to be a fairly mild, yet effective, sleep aid. I mostly use it to manage the clock on eastbound long flights (to fall asleep earlier than local time would have me do that.)
One thing to note about melatonin is there’s little consistency between the dosage listed on the bottle and the actual dose. Not a problem if it works for you but just something to be aware of, more info on the second heading here [0] if you’re interested
