Have had lifelong constipation problems. In 2011 suffered neck injury that left me with cord compression syndrome and worse constipation problems. Was taking stool softeners regularly and mag citrate occasionally. Usually had BM every 2 weeks, sometimes more frequently and at times 3-4 weeks. Take 2-3 Norco 5/325 mg, 1-2 flexeril 10 mg and 1-2 xanax daily. Is it safe to occasionally take dulcolax laxative, milk of mag or mag citrate with amitiza?
