Any help at all?

I am in need of some help. This is my situation. My mom has stomach cancer and she has been trying to treat it with Chemo. I've been trying to get her to take some alternatives, which I have found on this site, with it but my mom refused, because her doctor told her not to (of course). Anyways, she got worse and worse and they had to put a tube in her stomach to drain it, or she would be vomiting all the time. My mom always said that when she finds out the second Chemo isn't working then she'll start with alternatives, so great, now that she's ready to start she cannot eat anything! Is there anything I can do?
