Hey Soul,
Thanks for the headzup you're starting the anti-inflammatory regimen again... This time armed with more determination and the results from your 25(OH)D lab test.
For starters, the deficiency/insufficiency figures put out by the Institute of Medicine are meaningless for all but rickets, osteomalacia and osteoporosis...
The vitamin D3 experts and Jedi Masters of vitamin D3 therapy say any 25(OH)D serum concentration less than 50 ng/mL, (125 nmol/L) is deficient. They also say the optimum serum concentration is 60 to 70 ng/mL in order to take advantage of the full potential of vitamin D3.
See the following link for some fascinating reading about RCTs finding a long list of health problems either prevented or successfully treated with vitamin D3:

For us as CH'ers, our target 25(OH)D serum concentration needs to be 85 ng/mL or a range of 60 to 110 ng/mL for a therapeutic cluster headache response. An average 25(OH)D serum response in this rage requires a vitamin D3 intake of 10,000 as shown in the chart below.

As you can see the 25(OH)D time course response to dose can take several weeks and up to a couple months to reach a steady state equilibrium.
Accordingly, once you've been on the anti-inflammatory regimen for a couple days to make sure there are no reactions to the supplements, it's best to start an accelerated vitamin D3 dosing schedule to elevate serum 25(OH)D as rapidly as possible into the "green zone." This is where 80% of the CH'ers on this regimen experience a favorable response with a significant reduction in the frequency, severity and duration of their CH.
This vitamin D3 dosing schedule amounts to taking a total of 590,000 IU vitamin D3 over a 4 week period while keeping the other anti-inflammatory supplements at the same dose. The average 25(OH)D response is 60 ng/mL over the starting concentration.
The suggested dosing schedule starts with 20,000 IU/day vitamin D3 for two weeks plus a 50,000 IU loading dose once a week on top of the daily 20,000 IU/day dose. At the start of the third week drop the loading dose and lower the vitamin D3 intake to 15,000 IU/day... Continue this dose for two weeks then see your PCP for another 25(OH)D lab test.
If the results of this lab test come back at 80 ± 5 ng/mL, lower the vitamin D3 intake to a maintenance dose of 10,000 IU/day.
If the 25(OH)D lab results come back < 70 ng/mL, stay at 15,000 IU/day vitamin D3 for another week then drop back to the 10,000 IU/day maintenance dose.
Data from the online survey of 110 CH'ers using this regimen indicate 80% respond with a significant reduction in the frequency, severity and duration of their CH.. The response rate chart shown below shows 60% of them responded to this regimen within the first week and 90% responded within the first month.
