I also have used it from time to time to help me sleep, but not very often. When I do, it works well, though I tend to have more vivid dreams and find it harder to wake up in the morning (though I attribute the latter to being a little sleep-deprived anyway).
Made me curious, so I went looking for an explainer on exactly what melatonin is:
"Melatonin is a natural hormone made by your body's pineal gland. This is a pea-sized gland located just above the middle of the brain. During the day the pineal is inactive. When the sun goes down and darkness occurs, the pineal is "turned on" and begins to actively produce melatonin, which is released into the blood. Usually, this occurs around 9 pm. As a result, melatonin levels in the blood rise sharply and you begin to feel less alert. Sleep becomes more inviting. Melatonin levels in the blood stay elevated for about 12 hours - all through the night - before the light of a new day when they fall back to low daytime levels by about 9 am. Daytime levels of melatonin are barely detectable.
"Besides adjusting the timing of the clock, bright light has another effect. It directly inhibits the release of melatonin. That is why melatonin is sometimes called the "Dracula of hormones" - it only comes out in the dark. Even if the pineal gland is switched "on" by the clock, it will not produce melatonin unless the person is in a dimly lit environment. In addition to sunlight, artificial indoor lighting can be bright enough to prevent the release of melatonin.
"The amount of melatonin released at night varies among individuals, but it is somewhat related to age. Children on average secrete more melatonin than adults, which decreases further with age. However, research has shown that older people with sleep problems do not always have lower melatonin levels than people who experience normal sleep."
I also came across this, which interested me because I have ADD:

And it is good to know that it does have some drug interactions:
Antidepressant Medications
Antipsychotic Medications: many of these medications are now being used in treating children with ADHD and Bipolar disorder
Benzodiazepines
Blood Pressure Medications
Blood-thinning Medications, Anticoagulants
Interleukin-2
Nonsteroidal Anti-inflammatory Drugs (NSAIDs)
Steroids and Immunosuppressant Medications
Tamoxifen
