Kerry, In our case the sleeping 24\7 was normal. John had 33 rad. txs and from the 3rd week on, he slept from the minute he got home-excepting bathroom breaks and my waking him up to do a tude fee- until he had to go to rad the next day. After treatment was over, he slept almost around the clock for a month or longer. I remember being afraid that I would come inato his room and find him dead during that time. It was a really scary time. I think it is a way for the body to recuperate. It's tough, but you gotta hang in there. Amy
