Seems a bit long too. When I have a scope I am asked to stop eating anything with seeds a week before hand, that's okay as I cannot tolerate anything with seeds. I also have to go off blood thinners a week before. However, I am allowed solid foods up until 24 hours before the procedure. Then I have to drink a jug of that awful stuff (cannot think of the name of it; Peglite?) during the last day before to clear my bowels, and drink only clear liquids.
