Hello everybody

I am in need of fiber. I would rather not take any more pills, theres too many already. I am anemic and take iron supplements, which are very constipating. I bought the "sugar-free" orange flavored metamucil yesterday. I searched the container for any mention of sugar substitutes, but there was no mention. I got home and looked on the internet and it contains aspartame. Yuck!What does everybody use?........................Thanks..B
