Health Research & Patient Advocacy

I turned the worst pain
in medicine into a
research obsession.

Episodic cluster headache since 2013. Over a decade of sustained silence via the Vitamin D Regimen. I'm a patient, a researcher and a staunch supporter of everyone fighting this condition.

My Journey

Thirteen years living with
the suicide headache.

I was first hit by cluster headache in 2013. Episodic, meaning it arrived on a schedule: November through March, every year, with a precision that was almost mechanical. For anyone unfamiliar with the condition, the clinical nickname tells you most of what you need to know. The suicide headache. Unilateral pain around the eye and temple, so severe that the only rational response is to pace, rock and wait.

I found the Vitamin D Regimen through the work of Pete Batcheller and the Cluster Busters community, and it changed my life. I have been in sustained remission for over eleven years. That experience didn't make me want to move on. It made me want to go deeper.

I became a researcher because the science deserved someone willing to read it carefully and communicate it clearly. I became an advocate because the community deserves better than it gets from mainstream medicine. I became a Cluster Busters supporter because they were there when I needed them.

The Research Hub

Every paper.
Every decade.
One place.

The Cluster Headache Research Hub is my attempt to build the resource I wish had existed when I was diagnosed. A single, searchable home for cluster headache research dating back to 1947, a corpus of community experience and an AI trained on the literature so patients and clinicians can ask real questions and get real answers.

It's currently open. That won't be the case indefinitely. If you want continued access once it transitions to invite-only, reach out now.

Access Notice CHRH is open now, but moving to invite-only access. If you would like continued access, please get in touch before that changes.

Research Archive — 1947 to present
Over 3,000 cluster headache studies curated from 1947 to present. Every major study, every landmark paper, indexed and readable in one place.
Community Corpus
Years of patient experience, treatment discussions and lived accounts from the cluster headache community, structured for analysis.
AI Inference
A language model trained on the CHRH corpus. Ask clinical questions, explore treatment literature and get answers grounded in actual research, not general knowledge.
Always Expanding
New research is added as it's published. The goal is a living, breathing research environment rather than a static archive.
Vitamin D Regimen

The protocol that gave me
eleven years of silence.

The Vitamin D Regimen for cluster headache was developed and refined over more than a decade of real-world patient data. Pete Batcheller brought this information to the cluster headache community and it changed the trajectory of countless lives, including mine.

I host vitamindregimen.com as a way to pay that forward. The site is dedicated to documenting the regimen clearly, accurately and accessibly, so that every person who finds it can understand what it involves and make an informed decision about trying it.

I don't make money from this. It's a resource. And it's there because I believe the information should be easy to find.

Hosted Resource
vitamindregimen.com

A dedicated resource for cluster headache patients exploring the high-dose Vitamin D3 regimen. Includes protocol details, supporting research and guidance for discussing it with your doctor.

This site exists to pay forward the work of Pete Batcheller, whose contribution to the cluster headache community is immeasurable.

Inspired Conversations

The conversations I wish had existed
when I was first diagnosed.

Inspired Conversations is where I explore cluster headache, the Vitamin D Regimen, patient advocacy and the intersection of science and lived experience. What started as conversations about a handful of seemingly unrelated topics has evolved into something I find genuinely exciting: the discovery that those topics are deeply connected.

Fatherlessness, cluster headache, vocal chord dysfunction, Vitamin D3. I'm still tracing the threads.
