I can answer some questions, but I don't have as much experience as others in this.

I'm not sure how you feel the day of a chemo session, I'd assume you'd feel quite nauseous and lethargic. But I also think after a year of chemo, that those feelings would regulate after a while?

It is an IV mostly, but some chemo drugs are capsules. It depends on the drugs used. When we do chemo on dogs, we take blood from them and then run the test (20 minutes) then we given them a drug to stop feeling nauseous. We then give the drug, now depending on the drug is how long it takes... some we give over 20 minutes in an iv bag, others take only 5 minutes to administer. So I suppose it depends on what cancer and what drug is used.

You need to be careful to avoid bacteria and viral infections during chemo treatments.

Chemicals in foods can cause issues as well, so often chemo patients go on a wholefoods diet, so most chocolates and wines use high levels of chemicals in their production, you can get preservative free wine, so maybe find one from SA? Also you can get organic dark chocolate which may actually be good for her.

I hope others have more answers for you!
