Hey Avalon,
Welcome to CH.com. You've come to the right place. Good questions too, but let's star with your headaches.
Have you talked to your PCP or a neurologist about your headaches? If not, you should. Headaches are not normal.
Regarding vitamin D3 taken as part of Dr. Stasha Gominak's regimen or part of the anti-inflammatory regimen many cluster headache sufferers here at CH.com take to prevent their CH.
Both regimen are very similar. Dr. Gominak and I have discussed both regimen and she convinced me to add the 3-month course of vitamin B 50. Both regimen result in better, more restful sleep. We also suggest the vitamin D3 be taken with the largest meal of the day to increase absorption.
We start with higher doses of vitamin D3 than Dr. Gominak. She shoots for a 25(OH)D serum concentration of 60 to 80 ng/mL which requires a vitamin D3 intake of 5000 to 10,000 IU/day plus all the cofactors.
As cluster headache sufferers, (CH'ers) we shoot for a target 25(OH)D serum concentration of 80 ng/mL and that requires roughly 10,000 IU/day vitamin D3 plus all the cofactors.
As you can see from the following chart developed by Dr. Robert Heaney, MD, it takes 5,000 IU/day of vitamin D3 to achieve a 25(OH)D response of 60 ng/mL, and that a vitamin D3 dose of 1000 to 2000 IU/day is too low to achieve a meaningful therapeutic effect.

Regarding the spaciness and foggy feeling during the day... How much sleep are you getting at night? I've survey results from 127 CH'ers taking the anti-inflammatory regimen and there are no reports of spaciness or foggy feeling during the day.
What other medications are you taking?

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:

If you can’t get to a Costco outlet, a CH’er in the UK has found a source for all the needed supplements at iherb.com. See his post at the following link for details on how to order them 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, magnesium:calcium ratio. Many of us have found 400 mg/day magnesium is sufficient.
We've found that taking a vitamin D3 dose of 5000 to 10,000 IU/day depletes magnesium rapidly unless we take at least 400 mg/day magnesium... Hand and leg cramps are an indication you're not taking sufficient amount of magnesium
Hope this helps.
Take care and please keep us posted.
