Zofran was the nausea medicine they gave me and it worked pretty well. I also endorse what Bobert said although my worst nausea was while I was in hospital and didn't have access. Besides the nausea it helps control pain and in keeping a serene, positive outlook.
I would also suggest avoiding food that you really like for the time being. There are some foods that I used to enjoy that I no longer have the stomach for because I ate them during chemo and got sick. I doubt I'll ever eat popcorn again.
Keep fighting the good fight.
