Cheryl, I didn't have the problems your dad is having. My lips weren't very dry and on the few occasions where I needed something, chapstick did it for me. As far as the cisplatin, I had a problem with the first antinausia meds they gave me in the hospital. After they changed that, I had no nausia problems to speak of. Cooking sometimes bothered me, but not enough to get off the couch and go to another room, so it wasn't that bad. Have them try some other antinausia meds before administering the cisplatin. That may help. I got to the point that I left the hospital the day after the cisplatin was administered. Hated being in the hospital.
