I am not at all qualified to advise for this situation because I have not experienced or dealt with high numbers like this, with kidney disease as well, although my husband did have cancer. When he was in the hospital, they let him eat what he wanted, and then gave him insulin shots. They sent vials home for me to give him shots, but he would not allow that, and I did not attempt it. He did not test except the night before he saw the doctor once a month, and he just lived in denial until he died. I can't discuss this any further. Dorisena
