Am due to have an endoscopy sometime soon, have had it years ago without sedation. I found it horrendous so I'm opting for sedation this time.
What still scares me is when I had the throat spray, I felt like I couldn't breathe for a few seconds and was suffocating and gagging for breathe.. 
Im wondering if anyone had the endoscopy with sedation but without the throat spray??? And was it ok?
