If you are as sick and tired of my GI troubles as I am, skip this post. However, I think that I have solved another part of the problem. I have noticed that the less dairy products I consume, the less unpleasantness I have (to put it delicately). So I am going dairy-free and taking Lactinex. Lactose intolerance is not the whole problem but certainly has contributed.
I have requested some cookbooks from the library on cooking dairy free. We shall see how this proceeds.
