I have been taking the following for six months or more and regularity has NEVER been a problem.

Two tablespoons of pysllium husk blended with 8-12 ounces of Diet V8 (various flavors). Once a day every day.

The Diet V8 is a fruit drink flavored with sucralose. It contains 3-5 net carbs depending on how much you have. The pysllium that I use gets me 14g of fiber.

Good luck!!

p.s. the aspartame in the Metamucil is supposed to be avoided. Find a good drink that you like if you can't find Diet V8. I have mixed it with lemonade and even Chocolate Soy milk (sweetened with sucralose).
