pabb - I have not been tested for celiac, but I did go on a gluten free diet for 6 months with no improvement of my symptoms. Also, thus far, it has been fairly overcast here in NH this year, so though I have been outside for long periods of time, I have only had enough sun exposure to get a slight burn on my face so far this year, and not much on the rest of my body. Once we have enough sun that I am worried about burning, I will start putting on sunblock =)

Also, I don't know if it is less expensive in other areas, but D3 5000iU tablets here are $20 for 100, which does not seem terribly inexpensive to me. Is there anywhere that sells greater than 5000 iU's? I was unable to find anything that seemed legitimate, even online.
