metamucil or other natural bulk forming fiber is safe for daily use but x-lax, senna, ect.is not because your intestine become lazy over time and the intestine cannot function without it making constipation worse. I use metamucil and podiem everyday and are very effective at releiving constipation. If you do buy podiem make sure it is podiem regular and not podiem with senna. Im not a dr. just a ibs sufferer with constipation.
