diarrhea
"I have a long history of IBS-D, which has grown worse in the past few years after undergoing chemotherapy for breast cancer.  The diarrhea has become severe and daily, and without lomotil, I could rarely leave my house.  It has helped tremendously, and I don't seem to have any significant side effects.  I try to take no more than one pill a day, in the morning, and it usually keeps me diarrhea-free until late afternoon, depending on what I eat for lunch.  Some days, it holds me all day.  I am very grateful for this drug, because nothing else I've tried has worked at all."
