Thank you for your response; believe me, I am not about to for-go any of the traditional treatments for Anything. I have seen that there have been clinical trials involving Vit D., so I wanted to know about anyone's thoughts/experiences; and I appreciate yours. My thought process is that if there is anything I can do to "enhance" treatment, then I would like to take advantage. For instance, one of my questions tomorrow at my rad simulation appt is to ask if there is anything I can start doing/taking now to be proactive, so that when treatments start I am that much further along in the game. So far the only thing I have done is stock up on some supplies- many of which I saw suggested on this forum.
As I have said, I feel the more I learn, the more I don't know, and I appreciate the wisdom of those who have gone before me.
