Hey Susan! My sister is in he same mode. Also starting Rads within the next few weeks. I would rather her start with it and only use it when needed but I will tell her until I am blue in the face.

Her surgeon wouldn't have it any other way. I hope that she could make it through with out any pauses in her treatment from dehydration. To be con't.......
