Hey Suzz,
Data from the online survey of 257 CHers taking this regimen indicate this regimen is effective for 80% of the CHers who start it with >75% reduction in the frequency of their CH in the first 30 days. 50% of the CHers who start this regimen experience a complete cessation of CH symptom in the first 30 days. I've worked extensively with the 20% who don't respond in the first 30 days. Better than half of them started responding once they started taking Benadryl (Diphenhydramine HCL) at 25 mg every four hours throughout the day and increased their vitamin D3 dose up to 15,000 to 25,000 IU/day. I'd also like to point out that this online survey has been running since December of 2011. The results are consistent year over year. I also have informal data on over 700 CHers who reported their response to this regimen on clusterheadaches.com. that I've collected since December of 2010.
As a member of the American Academy of Neurology, I receive reports on studies designed to prevent cluster and migraine headaches. That includes the latest RCTs using monoclonal antibodies to prevent cluster and migraine headaches. I also have access to earlier studies on the use of verapamil in preventing CH. None of these studies have a success rate in preventing CH as good as the vitamin D3 regimen. It also works while busting with MM.
There's a lot of data from the online survey available in the anti-inflammatory regimen treatment protocol at the following link:
