answer:I use it, my son uses it (as directed by his pediatrician) and my husband uses melatonin. OK, so I’m not using it tonight! I like using it during the week, I have a hard time with most sleeping pills – they are just too strong for me. Melatonin doesn’t knock me out, it just makes falling asleep easier. My son says the same thing. I take 3mg, it’s plenty for me. My husband (keep in mind he’s much bigger than me) takes between 6 and 9mg – usually 6mg. He says it does make him sleepy. I’m guessing because I don’t use it everyday, I don’t feel that I’ve ever reached that point where I feel I need to bump up in dosage. With all this said, without knowing your medical history (any medications you currently take) I would suggest you talk to your doctor, or at the very minimum, a pharmacist about any interactions with anything you are currently taking.
