Shalom Shooky,
Thanks for the detailed feedback. It appears you're starting to respond to this regimen so it may be just a matter of a few days to a few weeks before you're completely pain free.
That said, with your 25(OH)D over 100 ng/mL and you're still getting some hits, it appears "tuning" may be in order.
Understanding a little about vitamin D3 phamacokinetics, (what the body does to vitamin D3) and vitamin D3 pharmacodynamics, (the pharmacological effect of vitamin D3 on the body), may help in the "tuning" process.
Your serum concentration of 25(OH)D is near the high end of the green zone so the first part of vitamin D3 pharmacokinetics where the liver metabolizes vitamin D3 to 25-Hydroxyvitamin D3 a.k.a. 25(OH)D is working as advertised and you're taking sufficient vitamin D3...
The next phase where 25(OH)D gets metabolized to 1,25(OH)2D3 at the cellular level, requires another enzyme, 25-hydroxyvitamin D-1alpha-hydroxylase. This enzymatic process requires magnesium.
As there was sufficient magnesium to support the enzymatic process that metabolized vitamin D3 to 25(OH)D, it would appear there's also sufficient magnesium to support 1alpha-hydroxylase in producing 1,25(OH)2D3.
It's this extrarenal autocrine signaling path of vitamin D3 metabolism that occurs at the cellular level that appears to be responsible for the mechanism or mechanisms of action that prevent CH.
Molecular biologists have found that 1,25(OH)2D3 combines with retinoic acid, a metabolite of vitamin A (retinol) and that this complex molecule attaches to a gene at what are called vitamin D response elements (VDRE). VDRE contain a vitamin D receptor (VDR) and also a retinoic acid receptor (RAR).
VDRE target genes play key roles in cellular metabolism, bone formation, cellular growth, differentiation, cell death and in controlling inflammation.
Where all this gets really interesting is a 2010 study identified 2776 genomic positions occupied by the VDR and 229 genes with significant changes in expression in response to vitamin D3. 532 genes have been put forward as regulatory targets of retinoic acid... Accordingly, it’s very likely the suppression of cluster headache involves several of these VDRE.
Molecular biologists have also found VDRE contain zinc at the receptor attach points...
That makes one of the short answers in tuning the anti-inflammatory regimen in your case, increase the vitamin A (retinol) and zinc.
Finally, none of the cluster headache abortive or preventative treatments work very well if serum pH is low... Too much acid. The best thing to try in this case is an alkaline forming diet...

The GOMBS diet can also help. GOMBS stands for Greens, Onions, Mushrooms, Beans-Berries and Seeds-Nuts. A handful of each a day would be good for starters.
