Miralax Prep for Colonoscopy - Terrified

This is my first time on this board.  I would appreciate it if someone could tell me if  miralax with gatorade is horrible like the "golitely".  I vomited with the "golitely" and I don't want this to happen again.  Can anyone tell me if this is as horrible as the golitely?  I am being checked for Iron Deficency anemia and even though it is 2 years this January since my last colonoscopy, the doctor wants another one. 

Thanks,

Tonice

Yes, I suppose the nausea is due to the volumn of the liquid.  I shall start my prep a few hours before the time so that I can spread it out.  I, also, have to take the ducolax before the liquid.  Thank you so much for your quick response.

My colonoscopy is for the 31st of December.  The doctor is also going to begin to burn off a flat polyp that he found on my duodenum when he did my endoscope 2 weeks ago.   .. He wants a thorough check - so a repeat endoscope to begin to remove the polyp and since I am under, he wants to do a colonoscopy.  After that is done I will go for a Capsue Endoscopy .. I am going to start the prep earlier than it says on directions and take the miralax more slowly to try and avoid the nausea.  .. How much do you have to drink?
