Marshmud:  Yeah the prep is the hard part.. and first time you usually are nervous. Now-a-days they have new drugs. I had one in 2006 after a bad illness. When  it was over I was thanking  everyone for the virtual tour. I must have been a talker through the whole thing. LOL Course the drug they use wipes out the memory of it. You are still coherent so you can shift around.
