Fiss et. al.,
Yes, I have heard that Metamucil helps one to firm up if necessary or become the other way if necessary. I have heard of two people that it helped with diarhea which I find hard to understand. When I am looser, I am just so fearful of taking it and worry that it may make me loose, but I would prefer to be taking more Metamucil and less Miralax, and that is what I am going to work towards. Thank you for the feedback!!
