Hi Old duck
i sufferred terribly with nausea and sickness throughout chemo. You definitely need to speak to your onc. For me, they ended up changing the carboplatin to cyclophosphomide, gave me ondansetron wafers and gave me higher doses of cortisone for a longer duration than normal. It certainly didn't stop the nausea but it reduced it substantially and meant that I didn't have to spend extra time in hospital dealing with constant vomiting. Ginger can also work sometimes although I found it made no difference to chemo nausea. I hope it all starts to settle down for you soon. Take care. Karen xox
