You have 300 mcg of melatonin tablets and you need to take 5 mg how many tablets of the 300mcg do you have to take?

If you can't do that conversion, then you have no business risking your health.

Please ! Consult a pharmacist. Just walk up to the counter and ask him the same

question. It won't cost you anything, and you won't risk overdosing yourself.

This is your body and your life you're messing with. Whatever you do, DON'T go by

medical advice you get from anonymous weirdos on the internet. You have no idea

who I am, whether I know what I'm talking about, or whether I even care to try and

tell you the truth.
