> So please don't interpret this story as a reason to avoid any vitamin D supplementation. 1-2000 IU/day has been shown to be safe with long term use

I'll give you a more regular story. Some time ago I thought I needed to take D3 supplements after being exposed to all this PR pushing it and given that I don't eat food rich in it, rarely get sunlight, don't go outside in daylight (densely populated area, supermarkets work 24/7, etc.). So I bought some and took 2000 IU/day for a few days. Suddenly I started feeling numbness on the tip of my toes. After a bit of research I attributed it to D3, immediately stopped taking it, but numbness went away only after a few weeks. It's hard to see how taking it longer could have been safe.

So please don't generalize that 2000 IU is safe just because something showed that it was for some people in certain circumstances given certain country-specific lifestyle, foods, etc. I don't think a decent study on D3 safety even exists.

No offense, but this sounds like a bad diagnosis on your part. It takes more than a few days for Vitamin D problems to arise. The fact that the numbness took a few weeks to go away after taking Vitamin D for only a couple of days means it was most probably some other thing causing the problem.

It took a few weeks to go away completely, but got noticeably better just after a couple of days. I'm pretty confident in that diagnosis, as nothing else have changed.
