hello trt, I did'nt have alot of trouble with rad. causing any sickness. My heart goes out to you though. I'll be cheering for you because all of what the others have said is true. If you can hang in there. Me and my family will be praying for you and I'll be sending up a warrior cry for you. I know you can do this. Take one minute at a time and one treatment at a time if you have to. What helped me each day was just focusing on what I had to do right at that moment, it must have been pretty distracting for me to really focus because before I would realize it that task would be done and I would get some relief and move on to the next thing. Good Luck and You can do this. We are rooting for you. :-)
