Thank you for your recommendation. I think it is a good one. Before the last procedure I started with a laxative earlier than usual and not much happened-which is typical for me. The PA told me -after the fact- that I should have called her to update her on my experience. As you said I followed all of their directions every time and still get the feeling I'm at fault when the record says inadequate prep. I'll plant to start prep even earlier. Thanks again.
