Well, you take Zelnorm b/c you're constipated. While on Zelnorm, you're supposed to be having bowel movements. Once you stop taking Zelnorm, you'll go back to your original state, (for example, maybe you were only able to have a bowel movement once a week), or worse (maybe you'll only be able to have a bowel movement once every two weeks or week and a half. Understand?
