Clear Liquid Diet. Can I Take My Medicine?

I'm about to start my two day prep for a colonoscopy and enoscopy. I read that red food dye should be avoided because it looks like inflation when in your intestines, but green and yellow (lime or lemon jello) is okay? Does anyone have suggestions on food?
I currently have power-aid, jello, broth, apple juice, and Popsicles. It looks very sad for two whole days worth of food.

Also, can I take my medications during this 2 day prep?

• adderall - ADD medication
• dicyclomine - For stomach pain, anti-spasm i think
• Narco - from ER for severe pain
• Xanax - sleep/anxiety

It's really hard to get a hold of anyone at my GI office, so any information on the procedures would be welcomed. I was originally scheduled for 3 weeks from now, but got moved up thanks to my ER visit. I don't want to do anything to mess up my prep and have to do it again.
