I had a colonoscopy in May and the gastroenterologist told me he couldn’t finish because he said I had a lot of looping. He said that they would preform another in the hospital next month. June had the second one and same results. He put me on Linzess back in May the highest dose this doesn’t work. I too had to prep for 2 days. The only thing that works to get my bowels moving is Miralax twice a day and then taking 2 laxatives on Tuesday to go on Wednesday. People that doesn’t have this problem have no idea how much we have to do just to go. Scheduling a poo day I have just learned my cousin has to do the same thing
