Anita is right! I forgot all about it, but when I was having Cisplatin and the associated nausea, I rubbed oil of peppermint (had on hand as a candy maker) under my nose and it really did the job. I don't know why and at the time didn't care because I felt so much better. I cannot imagine how I forgot that! Give it a try. It is inexpensive and worked rings around the meds I was given.
