Really sorry to hear about your husband. I sincerely hope that he can continue to be as well as possible for as long as possible.
We lost my dad to kidney cancer last month. He had tried Sutent, which didn't halt his disease, and then Nexavar, which also failed. When it became clear the drugs weren't working, and that his disease was progressing rapidly, he stopped them on the advice of the oncologist. We were told he had a very short time left.
I had purchased DCA, and he had been taking it for 9 days when he died.
For the first three days on it, he said he was feeling a little better, and appeared more lucid. However I believe that he was just too ill for the DCA to help.
I can say that before he started Nexavar, he had been feeling better on the Budwig diet. For 2 weeks, his breathing was improved, his pain levels were better, he had more energy. Once the Nexavar kicked in, all those improvements disappeared.
Even though my story is not a good one, please continue to maintain hope, and leave no stone unturned. People can and do beat this horrible disease, even when their disease is advanced.
God bless you
