Pain and tiredness after taking vitamin d?

I was at the doctor yesterday discussing my blood test results. I was told that I have hyperthyroidism as well as a vitamin d deficiency. She didn't tell me what the actual numbers are though. She said I should take 2000iu of d3 daily as well as fish oil.

Today was the first time taking it and I feel very tired and out of it, slightly nauseous and have had some Sharp pains on my left side level with my left breast. Are theses normal reactions to this medicine after such a short time?

I read about the oils used to make them, but the brand I am taking, bluebonnet earth sweet vitamin d3 2000iu chewables, don't seem to have any oils in the ingredient list. What else could make me feel like this after taking d3?
