The next morning I asked Danielle what she gave me. She sat me down and said something I think about every day now.
"You don't have a sleep problem. You have a nervous system problem."
Most people think melatonin makes you sleep. It doesn't.
Melatonin only tells your brain what time it is. It signals darkness. That's all it does.
My brain already knew it was dark. That was never my problem.
The real trigger for deep sleep is a drop in your body temperature.
When your core cools by about half a degree, your brain gets a physical signal: the night is safe, you can let go now.
But a wired body runs hot. That signal never fully arrives.
So your body knows it's late. Knows you're tired. It just never gets told it's safe.
That's why you can be exhausted and still snap awake. It's not a character flaw. It's a missing signal.
