I'm new to the BB and have been very interested in the help so many of you have found with calcuim and fiber and colon calm.I would like to more about all this. I have suffered with IBS D for over 20 years. I'm so tired of it! and of the pain! and the Dr.'s just keep trying different medicine. I am on Lomotil at the present time. But only when I get a flare up. It is suppose to help with the colon spasams. I looked at the store at the Caltrate that some of you have mentioned. There were several types of caltrate. So I decided to get more information before getting anything. Looking forward to learning more! Thanks so much for having such a wonderful and knowledgable information!
