i had endoscopy and colonoscopy a few weeks ago. it wasn't so bad really, except that I had an "abnormal anatomy" due to an operation I had years ago. Had to be given a sedative during colonoscopy as I was getting stressed out by the pain.
Between the two, I say, endoscopy is the "lesser evil"
Just don't forget to take deep breaths to prevent yourself from throwing up
Hope everything turns out well for you
