Thanks for the advice and surggesions. I believe this is a depression issue. We go to the Dr again this week and I will speak to the Dr about it then. He hasn't been physically sick for a few days but he refuses to eat/drink enough.
The Dr's office can't give him fluids. It is very difficult to find an IV location when he is dehydrated and requires 'the best of the best' at the cancer center to administer the IV.
