Well ... you never know. I just figured more is better than less so I kept taking more. At one point, 15 mg with alcohol.
The point is that 300 mcg is 0.3 mg and you may have chosen the better dosage.

The researchers also discovered that the typical health food store dosage of melatonin, which is about three milligrams (or 10 times the dosage in the study), is less effective in treating insomnia. In addition, the higher dosage can cause potentially serious side effects, including hypothermia (low body temperature). The study also showed that the higher dosage elevated plasma melatonin levels during the day, which can cause a "hangover" effect in some of the subjects.
