Hi Ed, glad to hear your hiccups have gone. Kris had intractable hiccups with his Cisplatin. They would come and stay for hours then go for an hour or two before returning again. This went on for about 10 days. He used chlorpromazine and lorazepam and haloperidol plus increased his maxalon to 20 mgs three times a day along with stemetil.
We were told the Cisplatin caused them but I did read a number of papers that attributed them to the anti nausea meds.
