I know this post is a couple of days old, but I hate seeing someone go through this without even a "I know how you're feeling..."
I had fistula/abscess problems around my anus for a long time. I was a couple surgeries in before they started rx-ing different meds to try to help (but they hadn't figured out that it was crohn's yet), and I think the meds just made the over-all picture worse. The Asacol was the worst for me. It made everything I ate taste like lighter fluid. This did not help my nausea and dry heaves!
So, are you just not taking ANY meds at all in preparation for the scope? Or are you still on pills? Any change, whether adding or subtracting, had a tendency to make me nauseated for several days. Plus, the stress of knowing that a Colonoscopy is around the corner probably doesn't help!
My fistula always drained more (often feces) when I had D. In order to slow down my bowl movements and give my body a rest, I usually found relief by just eating chicken broth and jello. My fistula always seemed to appreciate this, as the D really seemed to make it mad.
Good luck with your scope... and I hope you and your doc figure out something to give you some relief!
