Everything you described is completely normal for what most OC patients endure while going thru rads w/ weekly
Erbitux chemo. The very best thing you can do is focus on your intake. Every single day from today thru at the very least you hit the 1 year post rads mark you should be taking in at least 2500 calories and 48-64 oz of water every single day. This really will help make a difference in how easily you get thru this. Pay close attention especially on chemo days and the day after you want to push your fluid intake to help flush the chemo (poison) out of your body. I know its not easy going thru rads, especially if trying to work too but it can be done and unfortunately it is necessary.
