Hello and I'd just like to say that, despite going through what she's going through, your grandmother is very lucky to have such a caring granddaughter as you.  I can only go by my own experience but with the Domperidone (no, not champagne unfortunately, but the anti-sickness tablets the hospital gives you) I found that I was able to eat normally.  Nothing special, just the same food that I always had.  After a couple of days, I did start to go off my food and didn't force myself to eat if I didn't want to/couldn't, but as long as I kept my fluid intake up, I was all right. Then after a couple of days, I was back to eating normally again.  Perhaps have a word with your grandmother to find out what she likes/doesn't like, what she would like as a treat and take it from there.  Let us know how you get on.  Good luck.
