What a wonderful daughter you are, and how brave is your mum. Good advice about various drugs for nausea. I found ginger ale good and small packets of salty plain chips, Baked potatoes and a few steamed carrots and beans. Also boiled eggs and toast. Cheddar cheese and biscuits. Smoothies with protein powder, banana and blue berries, soy milk as I am lactose intolerant. Nothing spicy. No big meals. Plenty of protein. Lots of fluids. Some people find turmeric drinks helpful but I couldn't face them when a kind friend made some. Also worth trying the sea sickness pressure point wrist bands. I found they worked a bit but pressed on a sore vein so I couldn't wear them.
I hope things improve as she goes along. Chemo seems endless but eventually it passes. Karen
