"Ok, I have been taking Viberzi for 3 Days. I’ve been living with the worst IBS with diarrhea you could imagine, for 30 years. I am so thankful for this drug. It’s like a miracle and I know you people suffering from IBS feel the same. Had some constipation hoping that will stop. 
But to not have this for 3 Days was like a treat for me. Taking 100 mg twice a day."
