irritable bowel syndrome
"I was put on viberzi. Took one pill before bed on Tuesday and one before bed on Wednesday 75mg each. To say this has been a nightmare is an understatement. Within an hour of the second pill I had severe abdominal and back pain. Also, pain that went into the right side of my chest. It is 12:00 Thursday and I haven't taken another pill nor will I, but I am completely worn out and still in full pain throughout my body. I was so hopeful for this. Be careful!"
