My doctor just put me on Amitiza (lubiprostone) - a newer med for treating constipation. I've been taking 1 capsule twice a day for about 2 weeks now. So far, it hasn't seemed to be any better than taking stool softeners and Miralax every day, but I'm going to give it another month. Maybe it would work for you.
