I Have Had Diarrheafor Over 7 Months Now. I Had

I have had diarrheafor over 7 months now. I had biopsies with a colonoscopy that showed I have Lymphocytic Colitis. I was prescribed Bumedeside and while I was taking 3 pills a day for 8 weeks, everything was working as it should and I felt great! Two days after decreasing to 2 pills a day, my diarrhea flared up again and increasing back to 3 pills a day did nothing. I was put on Lialda then Lomotil. They didn't work. My Dr. put me on Viberzi last Friday and have never felt worse! I have had an extreme amount of bloating, stomach cramping, vomiting and continue to have diarrhea. HELP?!
