kratom, all i can say is.wow

opiates stop the motility of your lower intestines. so stuff doesn't go much further, then, on top of it your body absorbs the moisture in your stool so it can get hard as well. Bad news for those with diverticulitis, in fact I am not sure that someone who has such severe constipation over and over again might not GET diverticulitis from opiate useage. Take frequent breaks, hook down a couple three stool softeners when you take your opiates and keep hydrated, that way, when the time comes you won't be shitting a baseball bat - AND plug up your toilet as well.

Fun fact, Immodium (Loperamide) is actually an opiate. It has difficulty crossing and, more specifically, staying across the blood-brain barrier. That's why in normal doses you don't get high from it, It just works on the opioid receptors in the GI tract. Yup, you have opioid receptors in your large intestine. That's why it plugs you up when you got the diarrhea.
