Melatonin quits on you mid-sleep.
Melatonin has one job: tell your brain the day is over and it's time to start shutting down. That's it. Useful, but not a complete solution.
Sure, it can nudge you to fall asleep faster. But by itself, it may not be enough to keep you there through the critical 2–5 a.m. window. That's when cortisol starts climbing back up and the calming signals that helped you fall asleep can begin to fade.
This is exactly why you can fall asleep at 10:30 without a problem... and then find yourself wide awake, staring into the dark at 3 a.m.
Taking melatonin by itself is like turning the key in the ignition and then walking away from the car. The engine started. But nobody's driving.
You already suspected this. Now you know why.
