Perfectly safe: Hi. While no study has ever looked at the safety/efficacy of melatonin and chlorpheniramine (the sedating antihistamine in Nyquil), what we know about their pharmacology suggests they should be perfectly safe in combination. Insomnia is awful and affects so many people! I wish you good sleep!

Melatonin: It won't hurt you to try melatonin for a while but it may not be as good as you hope. When you say you are not drowsy with nyquil what exactly do you mean? How long can you sleep at night?
