Hi Jen; Pretty well everyone feels that the rads are the worst of the two..and their effects are quite life changing especially if you lose your saliva glands (I did).
I'm eight weeks past an extended radical neck dissection for a recuurence, and still experience some discomfort. I started physio within four weeks of surgery and the edema and stiffness are slowly improving.
Like you, morphine made me a little crazy, so we went with codeine after surgery with more success. Codeine should come pre-mixed with a laxative- but regular senokot handled those problems.
You did so well with your rad/chemo even though it was a hellish experience, I know you will come through this part A-OK.
Good recovery and gentle healing is wished for you. Keep on posting.
