So I went for the colonoscopy and gastroscopy and had no sedation thinking it would be ok! I was wrong! It was horrendous! I gagged and brought up phlegm the whole time the camera was down my throat! Constant u til it came back out. My worry is can they still perform and see what they need to see? The lady doing it wasn't very sympathetic of kind and I worry it maybe a false negative if my stomach was constantly heaving?
