By the way, my D3 and D2, 25-OH levels at the end of November 2012 were 42 and <4, respectively. An endnote said the reference ranges have not been established.

So can you boil it down on the 40mg of Lipitor? I not only have the PN problem I am also experiencing significant memory loss. Other than cut my dosage in half with a pill cutter (my cardiologist told me as recently as a year or so ago that I should stay on the 40mg dosage) and take the CoQ10, what else should I do? Is damage already done irreversable?
