Sharon,
I'm so sorry your husband is not doing well, and I can't imagine what it's like for you as you take care of this man you love. I don't know if this can be used for everything, but my sister is on a chemo medication that's taken by mouth (pills) and although she's only had one round (1 pill five days in a row) she hasn't noticed any side effects from it. She has Metastatic Malignant Melanoma and it's in an advanced stage (she also has ascites), there will be no cure for her but I think this is supposed to help her with the problems she's having with her disease not cure her. She also had lost her appetite but has it back now, I don't know if the medication (chemo) is responsible for that or not. I know another woman who took an oral form of chemo for a different kind of cancer and she never had any side effects from the drug. Her's cured her of her cancer, but it also hadn't gotten to an advanced stage like your husbands or my sisters. I added that just to let you know these oral chemo's do have some punch, even if they don't have these toxic side effects. I don't know the name of either of these drugs, but the oncologist should be aware of this type chemo and perhaps he will try something like this to help your husband to be more comfortable. Don't be afraid to ask the oncologist about trying a different less toxic form of chemo, as they're there to help him be more comfortable while he's dealing this level of disease.
You don't mention where you're from in Tennessee, I'm just wondering where your husband is getting his care. I live in Alabama and get my care at UAB Health System in Birmingham, I'm very fortunate to live where I have access to this incredible university medical center.
Let us know how the appointment goes Monday, perhaps you already do this, but write down all your questions prior to going to the appointment so you don't forget to ask something important to you. Some patients even hand their list over to the doctor, that way you don't have to worry about forgetting to ask something.
Know also we've got you in our prayers and try thinking of us as being there in body with you as you walk into the doctors office together for your appointment (There is strength in numbers).
