Hi Doug,In my expereince, I too had the stomach pains on a daily basis, so I assumed it wasn't anything I was eating. In some IBS cases though it is brought on by a food reaction. The pain from having one wrong thing could affect me for a day and a half. Then I would stop eating and wonder why I was still in pain..not realizing it was still the effects of the coffee I had yesterday for example. I have also read, that sometimes one food can delay digestion thus causing a reaction a day or two later. It is very easy to overlook a possible food trigger or sensitivity in this case as well. I eventually realized the only stable thing in my diet was coffee..with milk. Gave up milk and then coffee and it made quiet a difference, not just in my IBS but my overall feeling of well being. Then I was still eating Luna bars...two a day and after drinking a glass of soymilk and being sick for two days, I gave up the Luna bars too as they are full of soy. I agree with you that it is somewhat in your head as well. Heck, IBS is aggravated by anxiety and IBS causes anxiety. Many people find signifigant relief not only by watching what they eat, but with relaxation techniques as well.Kari****Yikes...excuse my grammar, I was in a hurry as I was off to a meeting!!!
