Have ibs, bad periods even when on apri get really bad cramping where i pass out and bowel spasms, is there something better then apri that could help?

Diet changes: There are a couple of medications that I have used in my practice (not sure if they are available in canada). These are Linzess and amitiza (lubiprostone). However the corner stone treatment for most of my patients has been diet changes. I usually have them avoid processed foods and gluten for about 30 days. For about 99% of my patients these dietary changes relieve most if not all of their symptoms.
