Sorry to hear your issues. Me Probiotics before I eat seem to help majority of the time. If I start getting nausea I take another probiotic. Still haven’t figured out how to regulate between consumption and diarrhea. And it’s been over 2 months. Severe stomach pain seems to interact with the constipation . Miralax fiber don’t seem to help . Even my foods I have diarrhea from doesn’t always work. Then when I finally do get a bm 4 or 5 days later I may have the diarrhea and feel decent the next few days . I also take an Acid reducer helps with heartburn symptoms that i really shouldn’t have since my hiatal hurnia surgery in 2004 .
