You might want to post this as a new topic as your post is likely to be overlooked here. My doc treated me aggressively with anti-nausea for 4 days after each chemo and had almost no nausea as a result. Suggest pressing your doc for further meds until it passes. Everyone is different in terms of how side effects affect them; for most the peak nausea seems to pass within 4-5 days. Definitely call the doc and see if more can be done. Treatment is rough but we can get through this. Good luck!
