Eric,
Here are some things that worked "somewhat" for my husband when he was suffering from chemo nausea:

Peppermints. Simple, but seemed to help. He would sometimes just breathe in the smell and would get over an acute attack of nausea.

Sea bands. These are sold for seasickness and seemed to help a little. Our accupuncture practitioner friend also showed him some pressure points that helped.

Wishing you better and better days.

Anita
