@margot69 -I'd also like to include @bleulagoon, @lady1lake in this discussion because they have both had chemo. Hang in there! Chemo can make you feel ill for sure. If you are still nauseous than contact your doctor or infusion nurse.
here are some ideas for you. https://www.mayoclinic.org/tests-procedures/chemotherapy/in-depth/cancer/art-20047517

I have just started my second round of chemo. Cisplatin and Etoposide. My treatment yesterday was supposed to be a 6 hour treatment with Cisplatin first followed by Etoposide. When Etoposide was added, I had a severe reaction of strong back pain. Demerol, Dexamethosone, and later when I started flushing with heat, Benadryl were all added to the iv. A rest period to give time for the drugs, then Etoposide was started again with no issues. This happened on my first round too. When I awoke this am, I was very nauseous, and felt yukky all over. I did not want to eat, but cooked up some farina (cream of wheat). The more I moved and was physically active, the better I felt. I ate my breakfast even tho I was not hungry. I'm going to keep mild exercise in my 'tool kit' for when I don't feel good. Hopefully this is a tool for both of us. It's not a long trial, but did work this am. Blessings and good wishes for your journey. VLR
