I hope your appt. goes OK. I also suffer that constipation and found something that does work. Steal cut oatmeal. It has such alot of fibre in it, that it never fails me. You can get it in a health food store in bulk. It is cheap and taste a whole lot better than any from quaker oats etc. This also helped me to loose 65 pounds and keep it off. I try to eat it as often as I can. Hope you try it. ginnie
