Hey Alison,
Good question. You can find results from a survey of CH preventatives and abortives here at CH.com in the tab at the left of this screen titled "cluster survey." It will provide answers to the first part of your question.
There is another preventative that's proving to be effective for more than 80% of the CH'ers who try it. It's called the anti-inflammatory regimen with at least 10,000 IU/day vitamin D3. This regimen treats a vitamin D3 deficiency and inflammation from just about every source including CH.
Have your husband see his PCP for a lab test of his 25(OH)D. This is the metabolite of vitamin D3 that's used to measure its status. The normal reference range for 25(OH)D is a serum concentration of 30 to 100 ng/mL. The vitamin D3 experts say any 25(OH)D serum concentration less than 50 ng/mL is deficient.
CH'ers with active CH who have gone in for this lab test have all had it come back less than 40 ng/mL indicating a vitamin D3 deficiency.
Over the last four years over 600 CH'ers have started this regimen. The online survey of 127 CH'ers indicates 83.5% of them experience a significant reduction in the frequency, severity and duration of their CH. 60% remain pain free.

I've found the following supplements shown by brand in the photo below are formulated with most of the supplements we need. I buy them at Costco, but you should be able to find similar formulations at most Vitamin Shoppes, supermarkets, Wall-Mart or over the Internet:

The vitamin B 50 is not shown. You’ll need a 3-month course of vitamin B 50 to handle any deficiencies among the seven B vitamins. Although the Super K with vitamin K2 complex isn't essential in preventing CH, it is needed to handle the increased serum calcium made available by taking vitamin D3 at the doses we take.
There are a growing number of studies finding the super K2 complex helps direct calcium away from soft tissues and arteries directing it instead to bones and teeth improving overall bone mineral density.
There are also a number of studies that have addressed the optimum ratio of calcium-magnesium supplements. The general consensus is to keep these two supplements at a 2:1 ratio. Many have found 400 mg/day sufficient.
Most CH'ers who have started this regimen in the last year and had their 25(OH)D results come back below 30 ng/mL, have used the accelerated vitamin D3 dosing schedule and found it got them pain free faster than taking the maintenance dose of vitamin D3 at 10,000 IU/day... The accelerated vitamin D3 dosing schedule follows:
On day one, take the entire regimen with 10,000 IU/day vitamin D3 and two of the Omega-3 Fish Oil liquid softgel capsules along with one each of the remaining supplements the first day.
If there's no allergic reaction to these supplements (very rare), take 20,000 IU/day vitamin D3 for the next two weeks along with the rest of the regimen.
In addition, for the first two weeks take a 50,000 IU loading dose (ten of the 5,000 IU vitamin D3 softgels) once a week on top of the daily dose for two weeks. The day of the loading dose you'll be taking a total of 70,000 IU vitamin D3.
After two weeks on above vitamin D3 dosing schedule, stop taking the once a week loading dose and lower your daily vitamin D3 intake to 15,000 IU/day. Continue at this dose for another two weeks then lower the vitamin D3 intake to a maintenance dose of 10,000 IU/day. At that point see your PCP for another lab test for 25(OH)D.
If you total the vitamin D3 doses you'll be taking 600,000 IU vitamin D3 over the 4 week period. This should elevate your 25(OH)D serum concentration by 60 ng/mL, (150 nmol/L) above your starting level. Assuming that starting level was less than 30 ng/mL, (75 nmol/L), your serum concentration should be around 85 ng/mL, (212 nmol/L).
If you're like most of the other CH'ers who start this regimen, you'll experience a favorable response within the first week to ten days. Migraineurs sail through their usual cycle times with nary a twinge...
Regarding the safety of this regimen. Long term dosing with 10,000 IU/day vitamin D3 is very safe. Your skin can make 15,000 IU of vitamin D3 in as little as 10 minutes if exposed to the UV-B in direct mid-day sunlight clad in a bathing suit without any sun block.
There haven’t been any posts or reports of vitamin D3 intoxication since I developed this regimen in October of 2010. Again, over 600 CH’ers have started this regimen since then. Other than an occasional upset stomach from the magnesium or Omega-3 Fish Oil, there haven’t been any adverse reactions that required medical attention. You can’t say that about verapamil or any of the other pharmaceuticals prescribed to prevent CH.
Again, the above regimen of vitamins and minerals is called the anti-inflammatory regimen. At 30 to 45 cents a day, depending on where you buy your supplements, this is the most cost effective and safest CH preventative available to us. You can read more about it at the following links:
