Thank you for your very quick reply. We are new to this board and are learning every day. I'm so thankful my brother showed me this site. Would the fast you spoke about help to clean the liver and bowels? He's used to fasting because that is what he has to do when the pain comes. My biggest concern is his consitipation. I was thinking about ordering Dr. Schule's Intestenial Forumula I and also the Super Food. I'm not familiar with Colosan that you spoke of. Do I order it on line, or is available at a health food store? Sorry for all the questions, I'm still leaning. Do you think the Colosan would be better than the Instestenial Formula?. I finally feel like we have some hope. The doctors keep saying there is nothing more they can do. Thanks again!!
