Hugs Jaime, from one who's been there!

I had a colonoscopy a few years back which showed a bowel tumour, so I had to go back and have a hemicolectomy and trust me, I was more worried about the prep than the consequences of the operation.

It was a piece of cake! Here in Oz there are 3 or 4 bowel preps available, and it depends on your doctor as to which one they order. I had one order Glycop-prep and that's 3 litres to drink.

For the bowel op and the post op check colonoscopy, I was ordered Golytely and that was just 2 glasses of prep washed down by lots of clear fluids.

The preps do clean you out but I didn't get any cramps, and each time I had enough time to make it to the bathroom. Don't plan on leaving the house, that's all.
