About Our Methodology
FOUNDER'S STORY
Why I Created GoZzzz
For almost 10 years, I could barely sleep. I tried medication, melatonin, meditation. Nothing truly worked.
Then I spent another 10 years studying the science of sleep — research by research, study by study. Walker, Huberman, Czeisler, Breus — I dove deep into every published finding.
GoZzzz is the program I wish I had found at the beginning of that journey.

José Nilton, Founder of GoZzzz
Today I sleep 7–8 hours on virtually every night. And you can too.

Does this replace medical care or treatment?
No. The program is educational and habit-focused; it does not diagnose or prescribe. For health concerns, see a licensed professional.
What is chronotype personalization?
After a short quiz, content can highlight guidance that fits your sleep profile (e.g., morning vs. evening tendency) — not a clinical assessment.
