Oh Boy, Lois, when I saw the word "hallucinate", I cringed. DEaling with bad reactions to drugs was one of my worst experiences with John's tx. And caused many sleepless nights- sitting with him-trying to keep him in bed- talking to the "people" in the room with him, remakeing the bed 10 times a night. You will need to be VERY firm with the Docs about trying ato come up with a pain med athat Buzz can tolerate- and each time he tries a new one, get someone to explain the posible side efects to you first- and how to quickly recognize them. Have you discussed the fentanyl patch? [many love it-John went bonkers on it]If some of the pain is thrush related or mucositis-treat for that. But the over all pain that comes with radiation is a challange. This is going to be trial and error for sure, and I feel for both of you because you both are going to get really tired.
