For those of you who have IBS or chronic constipation (from medications or other reasons) try this stuff. It really does what it says! I have both of the above. I used to take Zelnorm before they pulled it off the market it and it was the only thing that helped with IBS. Then I went into Chronic severe constipation due to medications and nothing worked (added fiber, water, etc.), NOTHING at all. It was horrible place to be in let me tell you. I know someone else just recently posted about the same problem and I forget who now. I usually don't believe commercials but my SO said "try it" so I did ( here it runs about $5.47 for an 8 pack). That's about .68 cents for a little 4 oz cup of yogurt (that really tastes good too!). Expensive I think but compared to medications that don't/didn't work and nothing else working it's been the best money I have spent and will continue to spend for the relief. So yes, I am promoting this product!
