Hi, @dcat, and welcome to Mayo Clinic Connect. You'll note I merged your post with this discussion about melatonin, so that you could meet some of the other members talking about this topic. Please meet @contentandwell@eliana5@ladybirder. @mbabkk@lioness may also have some input.
I'd echo what @ladybirder said earlier in this discussion about consulting your doctor or pharmacist about any potential interactions between melatonin and your other medications.
