I started taking the Viactiv calcium chews to see if the calcium would help my D. I did three chews per day which is about 1500 mg of calcium. Although it seemed to help at first, I started having problems with bleeding and the D came back. This was very scary, having never happened to me before (bleeding). I noticed that the Viactiv has Vitamin D and Vitamin K in it as well. I concluded that it was probably the K doing that to me. I stopped taking it and the bleeding stopped immediately. Anybody else have that problem? I have been doing small meals throughout the day and that has helped significantly. I was one of those types who did three big meals a day with no snacking in between. I must say...doing smaller meals and having little snacks in between has helped a lot. Eating half my portion in a restaurant and getting a doggie bag for the rest was something that would never have occurred to me before, but it does help. Staying away from known triggers has also helped. I still need to taken an Immodium Advanced every once in a while for control, but for the most part, I'm doing OK now. This site and these boards have been a very big help and its good to know you are not alone.
