I just got labs back from my endocrinologist saying I had low Vitamin D. Considering I spend most of my day outside and drink 4 gallons a milk a week, because I constantly crave it, I was shocked to say the least. She told me to take 2,000 IU a day. My counts were low enough to cause the adult form of rickets. But I have narcolepsy so knowing whether muscle weakness is from that or the "rickets" is next to impossible.

Why am I so low when I consume so much? And calcium wasn't tested, so I have no idea where that's at.
