norman walker was a big believer in colonic irrigation, eating only fresh raw fruits and veggies, and drinking fresh juice. you may want ot look into irrigation, i myself have never had it done but after reading this book i think i may see about it. maybe ask in the "ask curezone" about colonic irrigation and see if anyone has had good results. sometimes it takes a while for the good things we do to outdo the bad things we've been doing. keep at it.
