Sleeve with Dr. O? Urbana, IL

Hi! Was wondering if anyone has Dr. Oliphant for a sleeve Dr. ?? He is in Urbana.  I am going to be having the sleeve on Sept 6th and I was wondering how everything went with some of his patients?  I go to a class on August 28th and I'll learn more but was wondering how long I'll be staying the hospital and such?? Thanks!
