Yeah just as Goofy said just concentrate on ya breathing and it doesnt take very long they turn off the lights so you cant see a great lot or at least they did when I was there, I have afriend who has 3 endoscopies with out spray or sedtaion. Just try the spray if its no good they will stop. As its happening your gag reflex kicks in but not usually sick they tell you to keep breathing the 1st time the nurse stroked my hair, and wiped tears away from my eyes from retching, its the wind thats strange, they said you would hear the wind i thought meant farting but it comes out of yiiur mouth like loud long burps. its strange but just another thing we have to get through before the op. Go with an open mind keep calm n do what they say. x
