Just for additional reference, my dosage of Xeloda during radiation was 1800 mg twice daily. I am 5"10, 176 lbs. During radiation, my main side effects seemed to be from the radiation (some fatigue, painful skin burning in the last two weeks and two weeks after last treatment and pain and spasms passing stools).

For cleanup chemo after surgery, I did four months of more intense Xeloda, 4000 mg for 14 days straight, with one week off before beginning the cycle again. I had pretty bad hand and foot syndrome from that and they eventually had to lessen the dose and cut down to 7 days on, 7 days off.

I'm sorry you're going through this. The good news is that the first few weeks of radiation are largely symptom free and the treatment does end and symptoms resolve. Your dose does seem to be about in line with what is typical. Wishing you all the best.
