Hey Cocktail,
Mike and Patik provided you with some great comments so I'll address a couple other points about the anti-inflammatory regimen. I'm a chronic CHer and I've taken the cofactors and conutrients illustrated in the following photo since 2011. I've been CH pain free ever since.

It's important to understand the roles of cofactors and conutrients taken in this regimen. The cofactors are essential in the pharmacokinetics of vitamin D3 (what the body does to vitamin D3) and its pharmacodynamics (what vitamin D3 does to the body).
In simple terms, the cofactors play an important role in the hydroxylation of vitamin D3 to its first metabolite 25-Hydroxy Vitamin D3, a.k.a., 25(OH)D (Calcidiol) and hydroxylating 25(OH)D to 1,25(OH)2D3 (Calcitriol), the genetically active vitamin D3 metabolite responsible for preventing our CH.
The cofactors also play an important role in vitamin D3 pharmacodynamics (preventing CH). For example zinc supports several essential enzymatic processes and is also found in vitamin D receptors (VDR) as a "Zinc Finger" thought to be responsible for attaching molecules of 1,25(OH)2D3 to strands of DNA to initiate genetic expression. Vitamin A (retinol) forms a dimer (two molecule polymer) with the vitamin D3 metabolite 1,25(OH)2D3 that attaches to a vitamin D3 receptor element (VDRE) to initiate genetic expression.
The essential cofactors are contained in the Kirkland brand Adult 50+ Mature Multi. This multi-vitamin and mineral supplement is formulated with nearly all the vitamin D3 cofactors we need. It just doesn't have sufficient magnesium or any vitamin K2 complex which is why I added the 400 mg/day magnesium and the Super K with advanced K2 complex.
The worry about calcium being contraindicated while taking verapamil is over blown. Cardiologists who prescribe verapamil for their heart patients also suggest low doses of supplemental calcium to prevent osteopenia/osteoporosis. Accordingly, the 220 mg of calcium in the Adult 50+ Mature Multi does not pose a problem reducing the effectiveness of verapamil in preventing CH. It does help prevent osteopenia/osteoporosis, so this is a logical and beneficial rationale for taking the Adult 50+ Mature Multi. It's likely the verapamil wasn't all that effective in preventing your CH or you wouldn't have started this regimen.
For reference I've had two sequential DEXA scans (Dual-Energy X-ray Absorptiometry) for bone mineral density (BMD) 5 years apart since starting the anti-inflammatory regimen and if anything, my BMD has actually improved.
Conutrients are responsible for the same anti-inflammatory and CH pain prevention as vitamin D3 so provide an additive effect to increase the CH preventative capacity of this regimen. They include the Omega-3 fish oil and Vitamin K2 complex (MK4 & MK7) in the LEF Super K with advanced K2 complex. For a detailed explanation why we need Vitamin K2 MK4, see the following link:

Bottom line, it's best to follow this treatment protocol by taking the cofactors and conutrients illustrated in the photo above by brand and dose.
Regarding the vitamin D3. I switched from the Nature's Bounty liquid softgel vitamin D3 over to the Bio-Tech D3-50 (50,000 IU water soluble (micellized) form of vitamin D3) in July of 2018 as illustrated in the following photo.

I've found the Bio-Tech D3-50 to be faster acting and more potent at the same dose in terms of elevating and maintaining serum 25(OH)D concentration than the oil-based vitamin D3 formulations.
Here's the bottom line foot stomper (something very important to remember). I took a download from the online survey database of 316 CHers starting this regimen since December of 2011 on the 4th of July. The overall raw efficacy of this regimen has remained consistent through the end of 2018 with 80% of CHers taking it achieving a significant reduction in the frequency of their CH from an average of 3 CH/day down to an average of 3 CH/week in the first 30 days.
What jumped out of the data I collected on the 4th of July was the raw efficacy (for episodic and chronic CHers) in the first 6 months of 2019. It jumped to 90% of CHers starting this regimen achieved a significant reduction in the frequency of their CH from an average of 3 CH/day down to an average of 3 CH/week in the first 30 days.
I've done a regression analysis of this 6-months of data looking for any reason for this 10% increase in efficacy to 90% and the only factor I could find was most of these CHers may have started this regimen with the Bio-Tech D3-50. I say this as all my post about this regimen since July of 2018 have mentioned taking the Bio-Tech D3-50 suggesting to take it instead of the oil-based vitamin D3 formulations.
I also updated my webpage at VitaminDWiki at the following link in July of 2018 with a photo of the Bio-Tech D3 50 Multimedia File Viewing and Clickable Links are available for Registered Members only!! You need to

I'll take another download of the survey data the end of 2019. If this trend continues, the efficacy of this regimen in preventing CH is greater than all the other CH prophylaxis combined.
There's another very interesting factoid. The download rate for the anti-inflammatory regimen CH (and migraine) preventative treatment protocol at the following link Multimedia File Viewing and Clickable Links are available for Registered Members only!! You need to

has remained constant at 20 to 25 downloads per day since I posted it on my VitaminDWiki webpage 21 Jan 2017 through 28 March of this year. Multimedia File Viewing and Clickable Links are available for Registered Members only!! You need to

within 24 hours of a webinar presentation by Dr. Brian McGreeney, MD, "Boston_Headache_Doc" at Clusterbusters, titled
Alternative Treatments for Cluster Headache during the 2019 Migraine World Summit, the download rate for this treatment protocol jumped to 160 downloads a day. During his webinar presentation, Dr. McGreeney spent 4 minutes discussing the use of vitamin D3 as a user developed and supported, very effective CH preventative.
The download rate since Dr. McGreeney's webinar presentation has remained at an average of 100 downloads a day. Between the 3rd of July and the 7th, od July, there were 916 downloads for an average download rate of 229/day. I think it's safe to say the word about the efficacy of this regimen is getting out.
Given CHers all over the world are aware of this download site at VitaminDWiki, I can only conclude this dramatic increase in the download rate of this treatment protocol is due to migraineurs who watched Dr. McGreeney's webinar presentation at the 2019 Migraine World Summit. I've additional evidence this is the case as I'm seeing an up-tic in PMs and email from migraineurs since Dr. McGreeney's presentation. They are now outnumbering CHers.
Take care and please keep us posted.
