New Colonoscopy prep problems

I've had Crohns for 18 years this is not my first time doing the prep and test but my dr has changed offices and facilities where he performs the test and I'm trying to do the prep but I haven't even drank the 1/2 gallon. I've only taken the dulcolax (never had before) and I can't stop vomiting and am beyond nauseous. I already feel like o got hit by a truck. I am out of time at work so am taking unpaid leave for testing so I really don't want to reschedule. Help?!?! Suggestions

Thanks. Yes they were able to do the test. I've never been able to or needed to do the full prep in any form given my disease. But I was worried since I couldn't and didn't drink any of the liquid prep because the dulcolax made me so sick. Now I'm just trying to get back to my "normal". Thanks for your post.
