The Moon is Blue,
Thank you for posting this poll. I find it very interesting. I have also followed your other post regarding this issue.
I have tried vitamin D in the past with my son with no noticeable results. He had a very low vitamin D level at that time. As he continues to struggle, we decided to go back and re-visit some of the things we have tried in that past. Since a doctor we had seen at that time had recommended starting with several of the 50,000 unit doses, I decided to start with that again. I don't know the exact specifics time-wise, but within a short time (I think one to three days) of taking the first (and only) dose, he took a very significant dive with his overall symptoms. After a few days I began to wonder if there was something that triggered that but had no idea. The D3 then came to mind, and I thought, no, surely not. However, I continue to be very suspicious and seeing this poll makes me even more so. At first I thought it couldn't possibly be, but now seeing reference to others having this problem makes me even more suspicious. I wish I had made notes of what happened when. I think it has been somewhere in the two to 2 week timeframe at this point. Over the past two or three days, he has been seeming to begin to approach something closer to his "normal" baseline, but he is not there yet. I still can't be sure this was the cause, but I am strongly suspicious. He has a tough road just at his "normal" baseline, but this was a very significant drop and I haven't seen a drop-off of that magnitude in quite a while. I am really kicking myself for coming up with this grand idea! We should have started at a lower dose.
There is no way to know for sure if the D3 was the cause, but he will not be taking any more any time soon, that's for sure as the correlation seems awfully close! Thanks for posting on this issue. It makes me realize that my suspicions of this as a possible cause were not out of line afterall.
