Negative Positive
Title: works great but gives pretty bad cramps.
Review: I gave it to my husband for 6 days and from the first day, it worked good for him. He saw black stool his frist day (next morning). He said he was pretty shocked on how much stool was coming out of him when he thought he was a pretty regular guy. He was definitely going a lot more than usual.He even felt his pants a little looser around the waist and his eating habits were the same.
