Hey Greeneyes,
As you appear to be responding to this regimen, I would continue the accelerated Vitamin D3 loading schedule at 50,000 IU/day vitamin D3 for another four to five days along with the rest of the anti-inflammatory regimen. This is a safe and effective way of elevating your serum 25(OH)D up near 80 ng/mL where at least 83% of CHers experience a significant drop in the frequency of their CH or a complete cessation of CH.
Poping and chewing the 50,000 IU of vitamin D3 softgels between your back teeth and swirling the contents under your tongue for 5 minutes without swallowing will help in absorption... I do this frequently during my 25(OH)D burn down tests where I stop taking vitamin D3 until my CH return...
I'm a chronic CHer and take an average of 15,000 to 20,000 IU/day vitamin D3 along with the rest of the anti-inflammatory regimen. I've also maintained an average 25(OH)D serum concentration around 140 ng/mL for the last three years. Yes, I know that is above 100 ng/nL.. I also know that the 25(OH)D lab test results are a very poor indicator of vitamin D3 intoxication/toxicity... If we were to equate a high serum concentration of 25(OH)D to vitamin D3 toxicity, there are several RCTs indicating the concentration would be well North of 200 ng/mL.
My PCP is comfortable with my 25(OH)D being this high (It's been over 167 ng/mL) as he has a copy of the anti-inflammatory regimen treatment protocol so knows as long as my serum calcium stays within its normal reference range... and it has... there's no real issue with vitamin D3 toxicity.
As the CH beast is still jumping ugly after a week of 50,000 IU/day vitamin D3, I would start a week to 10 day course of Benadryl (Diphenhydramine HCL) at 25 mg/day... If there's no joy at this dose and the CH beast is still jumping ugly, bump it to 50 mg/day.
Take care and please keep us posted.
