Colonoscopy Tomorrow! Help! :-o

I am scheduled for my first colonoscopy tomorrow morning and need to know if anyone has had any trouble with the laxative prep I am scheduled to take later today. I asked the Drs. office, and they really had no information to give me. They said I should just follow the "regular" instructions.....but I am scared. Any information on this topic is greatly appreciated. I had my RNY last July.

Im so sorry rose I dident get to computer to read your question Im sure by now its all done It will be fine I dont think anyone likes that stuff and you will never forget it
