Well, I had my first colonoscopy yesterday and found the procedure itself to be a breeze. I reviewed this board as I was preparing to start taking the Moviprep and I want to thank everyone for their ideas on how to best drink it. That being said, I will NEVER use Moviprep as prescribed again! It took me 2 hours to get the 1st liter down, even after chilling (I even semi-froze some), flavoring, chasing with other fluids and straws. The last glass didn't stay down long and I was dreading the next round. After the choking down the 1st 8 ounces of the second dose my gag reflexes kicked in full force and there was no way I could get more down. Luckily the first round did it's job very well without undue discomfort and the doctor didn't indicate any problems with performing the procedure.
I also would like to speak to the person(s) who devised this medication in order to determine why they feel the need to make the volume you have to drink so high. If they just want to ensure you get enough fluids, I am a 'big girl' and can be trusted to drink the prescribed amount of liquids, as long as they aren't so vile as to make it impossible. If this medication is the only option my doctor will permit the next time around, I will mix it into the smallest amount of liquid possible, add lime or lemon juice concentrate and do it in 'shots' followed by glasses of water to make up the volume difference.
Thanks again to everyone for posting their ideas, suggestions and sharing their experiences. It really helped me get through the whole ordeal much easier!!
