I had both done in March of this year. The worse part for me was the darn solution you have to drink the day before. It tasted terrrible

Let me give you a couple hints on taking it.
1. Make yourself a big bowl of jello - just make sure it is the kind you can take - no red, orange, etc.
2. drink both hot and cold tea, don't just drink cold things because you get really cold
3. make sure you chill the solution
I would take a big spoonful of jello, chug half the glass of solution, follow that with a sip of tea and then finish the other half of the solution, followed by another spoonful of jello. That was the only way I could get that stuff down. I did the lemon-lime flavor, but my Mom has always liked the orange flavor for the solution. We were given three flavors to add to our solutions (my Mom had it done a week later): cherry, orange and lemon-lime.
As for the procedures, they gave me three shots of something, after the first shot, I was is in la la land. I do remember waking up once and noticing there was a TV on and thinking to myself, "what in the world are they watching on TV"

I guess I said it out loud, because they told me "that's the inside of your colon". That is all I remember for the whole thing
They found one 3 mm polyp that they removed, but nothing else. The procedure was really nothing.
After reading through some of the replies, it looks like there are several different types of preps. I can't remember what mine was called, but I had to take four pills, wait an hour and then drink a gallon of a solution in 2 hours. That is how they do it for our procedure (my Mom did the same). I had to stop eating at 12 noon, the day before my procedure. I then started the pills/solution about 2 pm that day.
