For melatonin make sure you are taking a supplement that only gives you .25-.5mg, more than that can be detrimental. Most supplements do more and there's some stupid reason why (the correct dose was trademarked or something after an MIT study). Life Science (I think is the brand) makes a vanilla flavored liquid vial, I buy that and do 3-4 drops and the vial last a very long time since the dose is small. I would also consider taking magnesium glycinate at the same time as the melatonin, stuff is very relaxing.
