Hey Carrie,
Welcome to CH.com. Thanks for the informative intro, kind words and back brief on your experience with the anti-inflammatory regimen.
I'm not a doctor or a licensed nutritionist so my reply and comments are for information purposes only... Bounce them off a physician you know and trust who is also familiar with your medical history.
I don't think you're crazy... and from the information provided by other CH'ers in this thread, it appears you're doing the right thing by taking 20,000 IU day vitamin D3... calcium and all the cofactors... The data in this thread also suggests you just haven't taken this regimen long enough as evidenced by your serum concentration of 25(OH)D.
That data suggests a serum concentration of 25(OH)D of 54 ng/mL is still too low... but very promising after only two weeks... The collective data in this thread suggests you need to get your 25(OH)D up into the "green zone" of 60 to 110 ng/mL in order to experience the benefits of this regimen.
IMHO, it appears the doctors you spoke with who claimed that a Vitamin D3 deficiency is very rare are sadly ill-informed and their claim is ludicrous. Moreover, they may be need of some meaningful CME...
Doctors and medical scientists at Boston University Medical Center, Boston, MA claim vitamin D3 deficiency is pandemic... See the following link:

You might want to print out copies of both abstracts and present them to the doctors you spoke with about this regimen the next time you see them...
You can also tell them that 76% of the 200 CH'ers who reported starting this regimen have experienced a significant reduction in the frequency and severity of their CH and 64% of the 200 CH'ers are completely pain free...
Empirical results like this exceed the highest possible placebo effect for a cluster headache preventative... so this is not a joke.. and you're not crazy.
In the mean time, data in this thread suggest you hang in there at your present vitamin D3 dose of 20,000 IU/day. Most CH'ers who reported they've been completely pain free with no shadows for a few weeks, have dropped their vitamin D3 intake to 15,000 IU/day to see if that holds them in the pain free green zone... Many of them have also found it helpful to see their PCP for another 25(OH)D lab test at that point..
Take care and thanks again for the great back-brief.
V/R, Batch
