KC, it's VERY good to hear that the cancer has not spread!
If you have any questions about the RAI, just ask us. One thing my Dr. forgot to mention to me: when you go on the low-iodine diet, you need to check your multivitamin, as many of them have iodine in them. GL with everything and keep us posted!
By the way, I'm about 8 days post RAI and starting to feel good. I'm still a far cry from feeling 100%, but every little improvement is great! I'm sure it won't take long for you to feel better, too.
