Phil, You are so right about having someone to drive you home. I had a friend take me and of course I nodded off on the way home. I don't know how far some of you are from the nearest MRI machine, but for me it is either one and a half hours or 4 hours depending upon the direction and where I can get an appointment. I am very glad I had a friend to drive me, the second time. don't forget how to laugh (if you had seen me the first time you would certainly know how to laugh) Marling
