I've had IBS with diarrhea for years..no constipation. My stomach pain occurs after a bowel movement and can last for hours.Some times the pain is unbearable. I take Dicyclamine for spasms and practically live on anti-diarrheals. Mine was made worse by colorectal surgery that failed. My life is governed by my colon. I have to carry extra clothes in the car and wipes & underwear in my purse. My condition determines everywhere I go and has forced me to cancel many appointments or social events. I have "accidents" regularly. My doctor just prescribed 2 new meds but they are so expensive I can't afford them. IBS is a debilitating disease and more research should be done to at least ease the discomfort.
