Never felt my heart pounding so much as it is now am on way the hospital to have my endoscopy at 9.40am and my heart is racing just the thought of something going down my throat that shouldn't as I have afear of vomiting so this is really making me think that camera going down my throat will make me vomit I really don't think I can go through with it but I need it doing.... Is it really going to be so bad ?? I have asked for max sedation !!
