Suz - I just wanted to say that I have had 3 gastroscopies (down the throat) and 1 colonoscopy (the other one!!LOL). I cannot be sedated with that medication. When I had my colonoscopy, they gave me enough medicine for a 250 pound man and I was kicking and screaming. I begged for more medicine and told the doctor "you promised you'd knock me out" ....to which he replied "if I give you any more, your heart will stop!". I am such a hyper person and I can't relax.....so thus the reason I watched the screen while they did it and acted like a freakin' idiot cuz I was under the influence of drugs.....just not out of it. Anyway, what I wanted to say.....is even that I'm aware of whats going on when I've had all of my tests.....the colonoscopy is MUCH Worse and hurt a lot more than the gastroscopy (down the throat). They sprayed my throat with something and I remember them telling me to swallow, swallow, swallow, swallow....but I don't remember feeling any where NEAR the discomfort I felt with my colonoscopy......so don't be scared. I'm sure you're probably not as hyper as me and the drugs will probably work on you. I also take Nexium for my stomach and Librax for Irritable Bowel Syndrome which I've had since I was a teenager. Maybe you have IBS?? Do you get a lot of cramping and stomach pain with frequency (if you know what I mean)? Don't want to get too graphic here. Feel free to PM me and I can explain a bit about IBS. I used to work for a colon and rectal surgeon, have had IBS almost my entire life......so I know a little bit about it....although all of that being said.....symptoms can vary from person to person.
