I have a medium-serious gluten intolerance which manifests itself with gassiness and bloating whenever I have an excess of wheat. Someone recommended these pills as a way to help my digestive tract cope with my bad food choices; and they work better than I had hoped they would. I take a couple of pills before I am about to indulge - let's say pizza, or fish and chips - and the bloating, gassiness and discomfort don't happen. I still watch my diet. I'm not such an idiot that I don't know what's best for me. But every once in a while (and I'm talking no more than once a month) I get a craving for pizza, just plain old bread and butter, chocolate chip cookies, etc. - and now I can have a reasonable amount, satisfy my psychological cravings, and then go back to sensible eating. These pills also come in handy when I am eating out - particularly at functions where I have no control over the menu. If I take a couple of pills along, I can eat pretty much anything they put in front of me without dire consequences. I can't guarantee they will work for everyone, but they sure as heck work for me.
