Why can regular melatonin leave you wide awake in the middle of the night?

Typical melatonin supplements – the kind that are widely available in most nearly every grocery and discount stores – peak in your body 3-4 hours after you take them. They may help you fall asleep, but after a few hours, you will likely find yourself wide awake, tossing and turning, desperately trying to get back to sleep.

The result: You wake up feeling no more rested than you did without taking the melatonin!
