Erik, I agree with others that it is probably the chemo that made you vomit. Did the nurse give you an injection against nausea before the treatment and did the doctor prescribe the anti-nausea medicine for you to take before meals? I was given both and still I vomited twice throughout the entire treatment. Not too bad already compared with other patients. The nausea was something very very uncomfortable. I say it is the effect of chemo rather than radiation because the nausea usually appeared after chemo and the two or three days that followed and then I had a few days of easier life and the cycle repeated when I had chemo again.Nausea will not stay long and in my case, it went away in 2 weeks post treatment. Then my appetite returned and was back to normal nutrition.

Karen.
