Dave, I would eat normally. They give you some IV anti nausea meds before your cisplatin dose. I usually ate fine during the actual dosing, they served lunch at my treatment center, and when I could no longer eat I was able to use my gravity feed formula on treatment day no problem. The worst for me was the second and third nights post chemo.

I was getting weekly doses, the first week was miserable and it wasn't that I had to vomit, it was like a very low grade seasickness... Just enough woozy/uncomfortable that you didn't want to eat anything and sleeping was difficult. I complained to the nursing staff and on the second week they used a bunch of anti nausea meds that worked well. I still was not 100% but it was tolerable.

You can read my blog in currently under treatment if you want to know the medication they had me on. Can't remember it now. Everyone reacts differently so go in with a good attitude you might be one of the lucky ones.
