He has a pre op "checklist" online, he should have given you something for your endo (or another dr) to complete for surgical clearance about 5 days before surgery (blood work etc). The actual prescriptions you will get the day before at your pre op visit. The hospital calls the day before to confirm what time you're coming in, warn you that the waiting room is cold etc.
Dr garramone's staff/office are very helpful, call with any questions.
Just went through this last week, hope it helps and good luck!
