There is a lot of information here how people fared on IMRT.
The response (side effect) to the treatment varies wildy, in some cases it does not seem to be a big deal.
It is probably best to expect that it will be miserable and prepare for it..... but also that there is an end to it.
In addition to what girlcat says also make sure that you get sufficent nutrition during the treatment.
