Hey Slacker,
I've gone over your past posts on this regimen... You're taking the right supplements at the proper doses and it appears you've good control over your 25(OH)D serum concentration.
Skip the calcium for a 3 to 4 days up to a week and keep all the other supplements the same. We've had a handful of CH'ers, both episodic and chronic with 25(OH)D serum concentrations in the high end of the green zone who were still getting hit... Dropping the calcium for a few days to a week helped most of them achieve a favorable response.
Two CH'ers with 25(OH)D serum concentrations comfortably in the green zone 60 to 110 ng/mL, responded in less than 24 hours after cutting their calcium intake.
We continue to learn more about the anti-inflammatory regimen thanks to posts from CH'ers like you. That said, its' not clear why some CH'ers continue to get hit with excellent 25(OH)D serum concentrations.
My guess at this point, and it's just that, a guess... is there are a couple possibilities in play and one or both may be keeping you from a favorable response to this regimen...
The first is a low systemic pH (too much acid) which can play heck with just about every conventional CH medication including oxygen therapy making them less effective.
The second possibility involves the second phase of vitamin D3 metabolism where 25(OH)D is metabolized into 1,25(OH)2D3, the active hormonal metabolite we think is responsible for triggering the genetic expression that down-regulates/suppresses the production of CGRP that is present during cluster headache attacks.
Drinking a baking soda tonic four times a day, an hour after each meal and right before bed should help elevate a low systemic pH... You make this tonic with a half teaspoon of Arm & Hammer baking soda in 4 ounces of water... The directions are on the back of the box.
If you detect any improvement after starting the baking soda tonic... then a change in diet may help. A GOMBS diet is one of the best ways to help alkalize the system.

Improving vitamin D3 metabolism to 1,25(OH)2D3 by cutting calcium for a few days to a week is still a shot in the dark... The relationship between calcium and magnesium is a yin yang thing... They work well together if the mix/ratio is in balance.
As magnesium plays an essential role in nearly every enzymatic reaction in the body, upping its ratio with calcium for a few days may be all that's needed to improve vitamin D3 metabolism to 1,25(OH)2D3.
Hope this helps.
Take care and please keep us posted.
