IBSC is the pits! I’ve had it for at least 50 years and it’s no picnic! The only regime that I have is morales in my morning coffee. Then, I need at least 1hr. on the potty to get relief. This usually works. For me, it’s a “mind game!” My brain wants to control my movements. I also go to an acupuncturist and as corny as it sounds, he gives me some needles for constipation. My protocol is not perfect but I can lead a fairly normal life. Good luck to you!!
