Thanks for responding, Harry. I do eat a lot of fiber...I am a strict vegetarian (I eat no meat or dairy) My stools are not hard or dry at all. I simply have no "urge" to go. However, after 2 or 3 days of not going, I feel terrible and my stomach makes disgusting noises. I began to use glycerine suppositories every day, about a year ago and they work pretty well, but I don't understand why I need them at all! I am 40/F. Any ideas??? Thanks a lot.
