Poor sleep is not the problem

It's just a symptom (here's why that matters):

If you see yourself in Person A, you’re in very familiar company.

My aim is to help you move toward Person B:

Person A: “I do everything right for sleep—no caffeine after 11, dark room, blue-light blockers, magnesium, breathwork, all of it. It’s helped somewhat… or a little… sometimes.”

vs.

Person B: “I’m generally not strict about it. I keep a sensible rhythm, but I don’t overthink it. I don’t need rituals to fall asleep. I sleep 7–9 hours, wake up once to pee, and fall back asleep within seconds.”

The Person A scenario is what I most often hear (& what I experienced myself for decades).

Today, most of my clients move toward Person B once we’ve identified and addressed their root cause(s).

The good news is that Person B is achievable for almost everyone—even in their 50s, 60s, and 70s.

The Difference Between Person A & Person B

One problem is that many of us think sleep itself is the issue.

It isn’t.

Poor sleep is just a symptom, like lower back pain.

Trying to fix sleep directly with another tip is like stretching for back pain without knowing its cause.

If the cause is a tight muscle, it might provide relief. But if the problem is a herniated disc, that same stretch could be make the problem worse.

The lower back pain (your poor sleep) keeps returning because the source—the actual problem—hasn’t been identified or addressed in a targeted way.

To move toward Person B, we need to stop solving for the wrong problem.
The next essential step isn’t another herbal tea; it’s asking the right questions.

That’s what I’m here to help you with.

You’ve probably already explored a long list of general sleep advice that only help “somewhat, a little, sometimes.”
