You'll be FINE! I had my scopes done before I found this site so I had no idea what it would be like and didn't have any expert adice on how to prepare! BUT...I got through it. The D was truly horrible, but no throwing up at all, promise. And to be honest, the D was so horrific and I was then so tired that I was falling asleep the instant I got off the loo, that I didn't have time to feel empty (which makes me nauseaous too normally)...and in the morning I got the procedures done and it was over!
