Most interesting, will bear that in mind. To this date I haven't encountered any "drastically wrong" symptoms with my d3 usage and frankly haven't heard that much about any adverse events linked to vitamin d3. If you feel comfortable with that then you could disclose what exactly is that adverse effect you've been experiencing, but I see that you try to avoid this topic so no pressure :)
It's not that I'm unwilling to publish the information: it is just that I despair of putting into words how I knew something was drastically wrong with my physiology -- especially now that 25 years have gone by.
