I'm also interested in this.
You know how on TV there's a commercial for some colon cleanse product, and they say you're carrying around 10+ extra lbs due to excess waste in the colon? DH & I are both sucked in to that concept and we both want to try it... But we want something very safe, natural, and safe for me while BF'ing.
So OP, I'm no help to you... but I've been meaning to post the same question!
