Cassie, I'm very sorry to hear that your family has to go thru this. I just finished my chemo treatments and I can tell you that they have come a long way in the treatments. There are a number of anti-nausea meds out there that work wonders and there are so many different chemo drugs. It surely isn't a walk in the park but it's not as bad as it used to be years ago. Everyone reacts differently to the drugs, some are able to work straight thru the treatments. I wish your family the best of luck and you have my prayers. There are a number of message boards out there that are related to cancer, that's where I found a lot of help, it's such a help to talk with people who have gone thru or going thru the same thing.
All the best to you and yours
Susan
