Glenn, I am not very certain about your question over weeks or months being the most difficult time. Everyone's experience is unique and can be reference to others only. In my case, the side effects of treatment accumulated to the 'peak' three months after completion. It was not the physical pain I could not endure; it was rather the emotional disturbance that I could not see light at the end of the tunnel that troubled me. I was flung into severe depression. I got to take anti-depressants (am still taking)but I started to learn how to accept these side effects as a price I have to pay in exchange of my life. With professional help and medication, I was able to go back to my work 6 months after treatment and gained back the weight I lost during treatment.If I had found support from other patients earlier, things could have been much better.
Karen.
