Hey Christine,
Glad to see you are both still keepin up the fight. I know you said "other than taking another medication", however, Rick has had the same problem since starting 5FU a year ago. Baclofen comes in a pill form, can be taken every 6 hours and works for him like a champ. Without it, the hiccups just continue on anytime he eats, drinks or rolls over in bed (go figure that one out). Much as he hates to take any more meds, this one seems to be a necessity and is effective.
Stay strong and keep up the good work,
Scott
