I've had IBS D for a long time now and recently I have been in a rut that I am really battling with. For the past week I have started taking Calcium supplements twice a day. I tried the fiber once but woke up in the middle of the night with a horrible case of D. Then the next 3 days I felt reletively good. Alot better than I have in a very long time, I felt like I might actually have found the answer but tonight as soon as I finished eating a bland meal of chicken and rice I felt very sick again. I've been following a strict diet according to Eating with IBS but now i don't know why the sudden attack out of no where. Help please! Also any advice about my situation with the Metamucil, should I try to go back on or what?
