Peter, It sounds as though you got lots of advice. Your dad sounds very much like mine. My dad has done very well with the Clozaril for the hallucinations. He still has some, but understands that they are not REAL - that is great help. His reaction to morphine is like my dad also. When he had a pacemaker put in over Thanksgiving one year, he was really agitated, paranoid, and totally different than usual. My mom told the cardiologist that he has a high pain threshold and does not need narcotics. He got so bad that the nurses complained and he was discharged early which was a big load on my mom. I went through the hospital bill and found that he had been given narcotics, Valium, sleeping pills, etc. I suggested my mom ask the neurologist write the cardiologist to prevent this. Unfortunately when the pacemaker malfunctioned 3 years ago, he would not listen and in order to calm him(the lower doses make him go crazy!) they gave him massive doses putting him in a 2 month coma. Still it is worth asking the neuro to let other drs. know about his paradoxic response to certain meds. My dad cannot even take Benadryl without getting agitated instead of drowsy. Good luck - sounds like you are on the right track. Aloha, Gail -- Gail B. Post, RN,MS,CSN Maryknoll Schools Honolulu, HI 96822
