Some days my husband doesn't have nausea, other days it is really bad. He is getting both radiation and chemo. We keep thinking it is the chemo b/c his nausea gets a bit better the farther away from the chemo treatment we get. Some foods also trigger the nausea, especially any type of animal fat. It seems everyone is different. Nausea is a constant companion. I think the radiation must cause some nausea b/c after his treatment each day he feels more nauseous. The meds help a lot when he has a bad day.
Hang in there......
