Hey Malibambo,
When you said your vitamin D3 was too high, what was your 25(OH)D3 serum concentration? Did a doctor tell you it was too high and stop taking vitamin D3? Did your doctor order labs for your serum calcium and PTH (Parathyroid Hormone)?
The 25-Hydroxy Vitamin D3, a.k.a., 25(OH)D3 lab assay is a very poor indication of too much vitamin D3 causing what is called vitamin D intoxication/toxicity. The lab assay for serum calcium is far more important. In this case, if the serum calcium concentration exceeds its normal reference range, this condition is known as hypercalcemia (too much serum calcium) a.k.a., vitamin D3 intoxication/toxicity.
In practice, it is difficult to take enough vitamin D3 to elevate the calcium serum concentration above its normal reference range. Most people would need to take vitamin D3 at doses greater than 100,000 IU/day for many months to push their serum calcium above its normal reference range.
The following 5-year chart of my labs for serum 25(OH)D3, calcium and PTH, illustrates how people can safely elevate 25(OH)D3 serum concentrations well above 100 ng/mL (250 nmol/L) without forcing their calcium serum concentration above its normal reference range.

As you can see, I've kept my 25(OH)D3 serum concentration well over 100 ng/mL (250 nmol/L) for 5 years yet my serum calcium has remained within its normal reference range so there was no hypercalcemia, a.k.a., vitamin D3 intoxication/toxicity. My PCP has no problem with my 25(OH)D3 as high as 277 ng/mL (692 nmol/L) as long as my serum calcium remains within its normal reference range.
Our immune systems keep us healthy if they get enough vitamin D3. The average adult needs 6,000 IU/day to 8,000 IU/day vitamin D3 to keep their immune systems capable of fighting off infections (viral, bacterial and fungal). As
CHers, we need a minimum of 10,000 IU/day to control and hopefully prevent our CH. In reality, what you did by stopping vitamin D3, was to prevent your immune system from functioning normally when it needed vitamin D3 the most.
To give you an idea what this really means, I've been taking an average of 15,000 IU/day vitamin D3 since 2011 and much higher doses to fight off an immune system response to allergens caused by spring pollen and fall mold spores. I've not had a cold or the flu in all that time. Moreover, I've not had COVID-19 since the Wuhan coronavirus landed in the US and I've been exposed several times. I also avoid the COVID-19 mRNA biologic Jab at all costs. There are a number of studies published that indicate the mRNA vaccines weaken the immune system leading to increased rates of infections, cancers, cardiovascular and autoimmune disorders. See the following link to VitaminDWiki.com for a lot of good information about vitamin D3 and COVID-19.

Bottom line, you should see your PCP and ask for labs of your serum 25(OH)D3, calcium and PTH. If your 25(OH)D3 serum concentration is below 80 ng/mL and the CH beast is jumping ugly, this is a classic indication you need to be taking more vitamin D3.
The best way to elevate serum 25(OH)D3 rapidly and safely is to take a loading dose of 50,000 IU/day for a week to 10 days then drop back to a vitamin D3 maintenance dose of 10,000 IU/day plus all the cofactor supplements illustrated in the photo below by brand and dose that I take and suggest to fellow CHers. It's also prudent to see your PCP for another set of labs for your serum 25(OH)D3, calcium and PTH after 30 days.
