Radiotherapy and nausea

Hi,

Just had my fifth radiotherapy session this morning for breast cancer. I have been suffering with nausea since my second treatment. All my treatments are early morning 9am. Today I had to leave work as the nausea was so bad. When I spoke to the radiologist about it the other day they said that nausea is not a side effect of breast radiotherapy and I maybe had a bug, but it is definitely the radiotherapy. It starts a couple of hours after treatment.

Just wondering has anyone else suffered with nausea?
