Thanks for the response and sorry it took me so long to say that! Dad's Dr. did give us the Senokot-S protocol to follow but it didn't work so hot. I've since bought him an enema kit and when he needs it, he mixes up his own "soap suds enema" to use. What seems to be working better than anything is flax seed! We started him on that about two weeks ago and he has been having a bowel movement nearly every day. He adds about 2 teaspoons to his oatmeal every morning and that seems to really help keep things moving. We just completed his 2nd cycle of chemo so we'll see how things go after this round. All of the anti-nausea meds they give him seem to bring things to a halt for a few days. How is your Dad doing?
