Hi everyone, i'm having a colonoscopy soon and i received a letter telling me i have to have a clear liquid diet for 2 whole days prior to the proceedure. I have pbc and take urso. The urso states i have to take them 3 x day with or just after food ! Do i continue to take urso without food for these 2 days ? Has anyone else taken urso without food and if so what effect does this have on the digestive system.
