Hi all, I was supposed to have a virgin DS tomorrow but the doc's office called yesterday and canceled due to my pre-op ekg. I apparently now need a cardiac clearance. Until yesterday I didn't know there was a cardiac issue. So, I'm bummed. I am planning to stay on the pre-op diet they have me on but continue the coffee they wanted me to stop months ago (small consolation). I think it will all work out but I was so mentally and emotionally ready to get "switched." So disappointed.
