MRI and c'oscopy prep?

I have to have an MRI of my small and large intestines on Wednesday before my surgery.  When speaking about this, the surgeon said I didn't need to do any prep.  When I received the instructions and appointment reminder in the mail, the secretary requests liquid diet the day before and products that you use for c'oscopy prep.  I would prefer not to, as I must take myself to that appointment and would prefer to not be weak/sore/tired/hungry from numerous bathroom trips and no nourishment.

I would prefer to eat my regular diet, only changing 'dinner' to a liquidy soup and waiting for after the MRI for breakfast.  I can bring a banana.

I plan on calling the Surgeon's office tomorrow, but has anyone had to clena out their bowels for an MRI? 

******s called this afternoon to confirm my appointment and remind me about the liquid diet and magnesium citrate drink in the early evening. :-/
My 'stools' have been very liquid-y for the past several days and I am still contemplating not getting the mag/cit drink. But I don't want to do something to screw this up for me, so I'll probably crab and moan and drag my feet to the pharmacy to buy a bottle of that nasty crap.
See? The crabbing and moaning has started already.

Crabbing and moaning, moaning and crabbing. I'm waiting until after "Deadliest Catch" before I drink the Mag/Cit.

I just noticed your siggie. I want a box of kittens, stat!, too. I'll tell Hubby, but I'm sure he won't be impressed. *sniff* We have 10 cats, but none of them are kittens. Everyone knows kittens make you feel better!

I'm being bad. I haven't drank the Mag/Cit yet. I better go do it and get it over with...

11 kittehs, here. (all s/n and rescues)

Well, the reason for the clean-out was because they wanted me to drink some nasty, thick stuff to be able to do a contrast MRI. At least now I know. Still didn't make it any easier to do.
