Marilyn---can't answer the drug question, but have you ever tried having him take Metamucil (or its generic form) for the diarrhea? It works for me to control chronic diarrhea caused by radition therapy nearly 9 years ago. Ask his doc--but I take LESS water and MORE powder than would be used for constipation, twice a day. Just have to be sure not to get too much and block action completely. He could start with say a tablespoon in about 6oz. water, and see if it makes a difference--probably morning AND evening. His doc should know about this--I was told by my gastroenterologist to use it. A couple of years ago Peter got paranoid in a similar way from adding Mirapex(then the NEW drug) to his schedule W ITHOUT reducing his Sinemet. Does that suggest anything? The clinical trials of Mirapex found that Sinemet should be reduced by 1/3.........our first neuro wouldn't listen when I told him that, and P. spent 3 wretched days in hospital, being delusional. P. now takes a small dose of Requip, along with Seroquel and does well on that. So sorry to hear of the trouble you are both having...... Marilyn wrote in part: >It's been the month of Hell.
