Yes, the dosage to me is pretty extreme and especially given my weight.

The dosage of 50,000 IU was meant to be taken I think for 5 days straight (to boost the levels quickly) and then tailed off to taking it once or twice a week (if memory serves me) as a maintainance dose. But I never got past the first day or two before it became obvious it was affecting me. I had to lie down because of going off-balance and of course, other symptoms too.

It affected my hearing and eyesight to some degree also. Had nausea, acid reflux, dizziness, etc for months after quitting it. I rang the office to get help and they didn't care at all. Told me they'd get back to me and never did.

Got in touch with another doctor I go to (mainstream) and they were very concerned and got me in fast. He said that the dose is not unacceptable and that they are doing this now in patients, but he said in my case, it hurt me (due to the metabolising problem). But as I said, i don't completely agree. I've seen enough reports now online of what these big doses can do to people and sadly, long term too. Takes a long time to "wear off". If in fact it ever does, as I hear overdosing vitamin D can cause nerve damage?

Of course, it's usually denied that it's harmed other patients in this way. But it's interesting how many you find on the net that have been injured in the same way. They maybe right, but it's possible that not many people are put on such high doses here in nz anyway, so they may not be getting an accurate enough idea of what impact it can have.

So you're being very wise about dosing. I have heard great benefits from vitamin D, as long as one does not go for overkill. As with anything i guess.
