So sorry to hear that you have been diagnosed with IBS. I have had IBS-D for 27 years. Over the years, I have been told that I would have to live with it or I was given pills to calm the spastic colon down. The pills might help for awhile, then not! I do not take anything now. I am trying Digestive Advantage for IBS. But, I have almost finished a box and can't see the difference. I'm sure it'll take more than a box. If I have a real bad stomach 'issue', I take an anti-diarrheal pill (like Imodium). I hope you won't suffer, like I have. Take care.
