FYI The neurologist/sleep specialist DD saw a couple of years ago started her on 3 mg of melatonin and said to use it every night. It worked great for a few months and then was not so effective. We tried 5 mg which did the same thing - worked for a few months then not so effective. A parent here posted that she was told to go to a micro dose - 300 mcg - and it worked better for both her and her child. I have not found the 300 mcg in stores but have to order it online. It has continued to work (falling asleep faster and staying asleep albeit with all the restlessness I mentioned) much longer than the higher doses did. And I definately feel better about using a smaller dose.
