You don’t need another wellness routine. You need a protocol that survives Tuesday.
Real frameworks for women in their 40s who run actual lives. No woo. No $400 functional medicine consult required. Start with the free 13-page Wellness Audit.
No spam. Unsubscribe anytime. One useful email a week.
Most wellness content is written for women who don’t actually exist.
The “do these 47 things before 8 AM” crowd assumes you have a personal chef, a meditation room, and zero responsibilities. You have a job, kids, a 3 PM crash, a bathroom shelf full of supplements you can’t justify, and the nagging sense that the $200 magnesium isn’t really doing anything.
Build Your Protocol is a playbook library for women in their 40s who want frameworks they can actually run. No 12-step morning routine. No $400 telehealth consult. Just clear, opinionated, evidence-grounded protocols you can adopt in a weekend and adjust as you go.
The first playbook is the one you needed at 3 AM last night.
The 3 AM
Reset
By Kathryn Crosby
$29
The 3 AM Reset
For when you’re waking up at 3 AM and can’t fall back asleep.
- —The 3 AM Wake-Up Decision Tree — a printable that tells you exactly which lever to pull first (cortisol, blood sugar, perimenopause, or something else)
- —The 14-night reset protocol — what to do, in what order, and what to track
- —Supplements that actually move the needle (and the ones to stop wasting money on)
- —A real plan for waking up at 6:30 AM instead of 3:12 AM. Forever.
A methodology, not a vibe.
Playbooks, protocols, and a stubbornly evidence-led method for women who’d rather understand their own bodies than be told what to do with them. No tribes. No journeys. No supplements you’ll quietly throw out in three weeks.
Three roles. One operator.
The wellness industry uses words that don’t mean anything and we are tired of it. Here is the frame this entire site is built on.
01 · You
The operator.
You run the system. You decide what’s tested, what’s tried, what’s bought, what’s discarded. Nobody outsources this for you. That includes me.
02 · AI
The research staff.
It can read a hundred PubMed abstracts before your coffee is cold. It does not get to decide what you put in your body. It works for you, not the other way around.
03 · Your practitioner
The clinician.
A real doctor. Prescriptions, diagnoses, the things that legally require one. The wellness industry is not this. Nothing on this page replaces a clinician.
Kathryn Crosby.
I run a consulting company by day. I write Build Your Protocol because at 44, single mom of four, divorced six years, I got tired of being told to drink more water by people who charge $400 to say it. So I started building the frameworks I wished existed — using AI, evidence, and the same operator brain I use at work.
The playbooks aren’t medical advice. They’re field-tested protocols from someone who actually had to figure this out, written for women who don’t have time to wade through another listicle.
“I would rather be annoying than have you skip past it: most of what you’ve been told to buy isn’t the thing that would actually move the needle.”
