I think calcium carbonate is what you want to take to try and control the D. Calcium citrate is better for people that suffer from C.
The problem with long term Imodium is that people start using it as an everyday preventive even when not needed instead of using it just when they are having problems. Imodium can stop you up and dry you out very easily and cause more problems. When my doctor told me that my diverticulosis may be because I abused Imodiums and caused constipation all those years (I was IBS-D at the time), it caused parts of my colon to weaken and developed pockets.
Like Sarita said, there are times when its absolutely imparitent to take as a preventive but not good on a daily basis.
