In this episode, I walk you through the four functional lab tests I use to find the hidden imbalances that keep you from sleeping, even when you've tried everything else.

I also share what these tests uncovered for my client John after 25 years of insomnia and nearly a dozen professionals who couldn't help him.

You'll learn:

What a hormone test can reveal about why your mind races at bedtime
How your gut can keep you awake at night even if your digestion feels fine
The brain chemicals that decide whether you feel calm or wired when you're trying to sleep
Why hidden toxins can build up in your brain and disrupt your sleep, even if you live a clean lifestyle
What John's four tests showed and how his sleep changed
