No I really didn't. I just noticed a reduction in gas of a certain type. Before taking the probiotic I would gradually feel more bloated and full of gas as the day progressed. By the end of the day I would be in pure misery. I still have "normal" flatulence and that seems to depend on what I have been eating. But I have noticed a dramatic change in the bloating problem. The constipation is still an issue though.
