For anyone having fiber problems... I'm having great success with Benefiber. The ads are right, you really can mix it into anything and you can't taste it, and there is no texture change. I've even left it sit in a glass of tea (decaf) and sipped on it while watching TV and it never thickened or changed consistency.

Note: I've noticed a change in my weight loss with this too, plus the other... uh.... added "benefits" of getting enough fiber.
