Hi Karen,
I think it is really hard to give any suggestions, without really being there. It must be so hard to see him in this state. I had the same feelings with Hans, my husband, and I felt when he finally went to the hospital that he would return in a few weeks.
It is so hard to accept what is coming, I think we always will "see life" in our loved one. Karen, I feel for you, and I really don't know what to suggest. My intuition and my heart says accept for what is and cater to what ever he wishes. This is hard, but it may be the best for your husband and I only can say this after I went through a similar situation.
I think you should be worried about dehydration, because the pain medications without fluids can really affected his brain. I am not a doctor, and I hate to give you wrong advice, but I feel compelled to share this info.
Hans refused fluids and only drank a little just before admitted to hospital. After waiting for a bed, without IV and lttle fluids, for 24 hours Hans became for lack of a better word "crazy". It lasted 3 days and the nurses told me that this often happens because of dehydration and having a lot of pain medication. After 3 days, being on an IV, he settled down, but he told everyone that he had the worst days of his life(it was horrible for me as well). If you are able to get him on an IV that would be great, here in Canada that was not possible in home care.
If I can help let me know.
Take care, and a big hug,
Renee
