Insomnia
"Sometimes it works and...sometimes it doesn&#039;t. The effects are not as obvious to me as prescription medications. 6 mg seems to be my sweet spot; any more and it has no effect. I try taking it when I know my sleep schedule needs fixing and that I&#039;ll be awake late otherwise, and it can work like that when taken infrequently. But it&#039;s not my first choice. Can give me nightmares also. As a younger man (22 years old), I&#039;ve read that melatonin supplements work more effectively on older individuals, which may explain my hit-or-miss case with it."
