Hi - ditto what others have said - rads is generally worse than chemo - I found other than mild nausea chemo wasn't to bad. But everyone has their own level of tolerance and is affected differently. Rads will likely kick in around week 3-4 and last for a few weeks after treatment has stopped. I managed without a feeding tube as well. It is doable but you have to be willing to push yourself to get enough nutrition. Best of luck.
