diverticulosis questions

I'm interested in doing a liver/gall flush but I have moderate to severe diverticulosis (i.e. little 'pouches' or 'pockets' in my colon, that about once a year on average get infected). Also, it leads to a volatile, irritable bowel just in general. My concern is that if I dislodge a whole bunch of little gall stones, I might wind up getting one stuck in one of the pockets (diverticula) and come down with the grandaddy of all diverticulitis infections. Any ideas? As well, if anyone happens to know a good rememdy I could research for healing/toning my colon back into shape I'd appreciate that info too!
