I had a similar experience. I'm not 100% sure, but 95% sure that it was the acacia doing the same to me. I stopped taking it and started taking Benefiber and have felt much better ever since. Although I am C, not D. Haven't had C, gas (other than normal), or bloating since. Might want to try a different fiber for a few weeks just to see. Otherwise, it might be something else in your diet.
