It wasn't as bad as I thought it would be. I got scared when the nurse said she was going to bring my surgeon in there to watch the process because some patients don't do so well. For me, the hardest part was when she was squirting the lidocaine mixture in my nostril. I think it was 4 times she did that. But that deadened my nostril and the part I swallowed deadened my throat. Once she entered the tube in my nose, I didn't feel a thing. Then she warned me when the tube was about to hit my gag reflex, but I didn't feel that either. I did fine. After they have the tube in place, I laid back a little and she would give me liquid (squirted it in my mouth from a syringe) then I would swallow. Did this 10 times so they could get the images they needed. Then she had me take a deep breath and pulled the tube out of my nose.
Not saying I ever want to do that again, but I got all freaked and worried over nothing. You'll do fine. Just try and be calm. Best of luck to you!!
