i ditto the above posts. let me add two things. first raw fresh cabbage juice can cure even the worst stomach and intestinal problems. it really it a wonder worker. this is an old remedy that really works, you will be amazed. i would do a raw juice fast, with fresh made juice not that store bought stuff, with plenty of cabbage juice. add some apple lemon and ginger and you got yhourself a feast. juice fasts are fun and easy to do.
