Hey RyanZ,
I was exactly like you - never had surgery or any type of procedure. I am a RN with 15+ years of ICU experience - so I understand all about medical procedures; however, I was still very anxious about the EGD. But, let me reassure you it is a breeze - you will wake up in the Recovery Room after a great short nap and not remember a thing.
I am still anxious about my surgery. It is scheduled for next Wed, but I am sure it will go just as smoothly.
Good luck with your procedure.
