I am having problems with my 75 year old Alzy husband. Sometimes he is constipated, and then he gets the runs. Since he is so very slow and not quite aware, this is making for alot of cleaning for me. I don't like Metamucil, too thick. I do like Benefiber but not sure how much an older person needs. Or maybe there is something else that would help. I just want him to be sort of regular.....not sure the polite way to say it....I want him to have something firm rather than runny!!! Sorry. Not sure how to say it!
