Last couple of weeks my C has been on and off again...I know a lot of it is tied to work stress, as I am now able to go better and easier at home than at work, and it used to be the opposite.Anyway, for at least a couple of weeks if not longer, when I have been able to go, my stool has changed color and consistency. For the last couple of years, it was almost always light brown and soft. Lately it's been much darker and harder (not painfully hard, just harder). It's not black and there's no blood - I know to look for those signs.I have been taking some "Super Green" supplements - could those be responsible for the change? And what IS healthy/normal for color and consistency?Any info and experiences you can pass along would be helpful!
