I think everyone reacts different.
I got sick from the first Chemo You feel nothing as they load you up, sickness was like a bad flu
They tried alot of different meds, came up with I can,t recall that help some. The Radiations I was OK till about 18. I got thru it one thing I remember best my DR. said we will help you get thru this, and they did. I talked to few people that went thru it before me, the one thing I wish I would of done was the peg, I did not and it took longer for me to recover. I remember reading Lance Armstrong book while I was getting my first chemo, I never put it down till I was done. Good luck
