I have been using Metamucil Clear & Natural (the kind you can use in cooking & baking), 1 heaping tsp. in am and bedtime, for a few years. The large size says 56 doses, so it lasts about a month and is about $12. I just dissolve in plain tap water and take it with my meds. Practically tasteless and no grit. I usually order 4-5 at a time from drugstore.com, or Rite Aid on-line, and get free shipping.
