I have had IBS-D for many years, right now I am on buscopan for pain, and spasms, and Immodium to slow things down.I took 2 a couple of weeks ago, and it has not been too bad. Still able to go to the bathroom. Only once a day. The immodium slows the contractions down. I also eliminated chewing gum, carbonated drinks, and eat oatmeal 3 or 4x a week. Good luck.
