Query: Works Great!

I have a terrible sleep disorder. In fact, I take Lunesta every night and have for years. But, Lunesta doesn't help me fall asleep. It helps me stay asleep. I added the Melatonin a couple months ago - I take 10 mgs - and it really makes me very sleepy. Love it. The product came quickly and well packaged. I recommend it highly to anyone who has trouble falling asleep.
