Yes, years ago I started taking Benefiber and I got choric C for months. Really bad experience :-(
I usually use 2tsp whole flax seeds soaked in an 8oz of water overnight and then I eat them with my cereal. I ground them at home sometime. I'm underweight so I don't really worry about the fat grams. Plus is good fat, it won't make fat.
Blessings, Abi
