Course mastery
A 14-day, day-by-day protocol built on the two levers that actually govern sleep — light and timing — plus the honest chapters on caffeine math, alcohol, temperature, 3am wake-ups, and which supplements do anything at all. Comes with a printable tracker and a self-assessment that tells you when it’s a doctor’s job, not a protocol’s.

I read the research so you don’t have to. Practical, evidence-first guides on supplements, skincare, and sleep — written to be used, not skimmed.
