The procedure? You're asleep!
As NYC_SKP says, stay close to your bathroom!
Your doc will probably tell you what to drink the laxative with. Mine did.
Best of Luck!
What happened to him was pretty unusual. It's unlikely to happen to you...
It's a natural electrolyte replacer and I find it tasty. Some don't, so if you don't find something you like to replace those minerals 
it's the view I get all the time
I guess you don't have to watch the video if you don't want to. I found watching it a nice distraction from the rest of what was happening
Yet, I've always watched any medical procedure done on me if it's possible. Such as when I had the toenails on both big toes trimmed to the root for ingrown toenails. I couldn't feel a thing, so it was cool watching the doctor cut and kill the root with 100% phenol! They looked horrible for weeks, but have never bothered me since.
Watching the inside of my colon go by, or when the doctor would squirt water at some area to clean it better, was interesting, too. The only discomfort I had was when they had to get around a sharp bend. The drugs, though, kept me in a kind of mental twilight. They never made me drowsy enough to sleep through it. Just druggy-happy and painfree 
if so maybe you should double up on the prep or speak with your MD about it-or so my sister who is a vegetarian tells me-the rest of that horror story I'll leave to the imagination
and I was pretty well cleaned out when I did my procedure (at age-48.) Only some residue on the walls of my colon, and that might have been from the popsicles they said I could eat. On the video, the residue looked vaguely orange and was but a light coating. Nothing else!
encouraged to fart.
A LOT.
The one I used was only 2 liters, taken an hour after some pills, and I was able to drink it well chilled instead of lukewarm. The flavor wasn't as bad as I thought it would be; a little like a slightly salty lemonade (they had 4 or 5 different 'flavor packs' you could add). Doc said everything was fine, and I'll see you in 10 years (they used to be 5 years apart).
For the full experience, read Dave Barry's column on colonoscopy from the Miami Herald. It's probably one of the funniest things I've ever read... along with 'The Hitchhiker's Guide to the Galaxy' and 'A Confederacy of Dunces' (both of which had me laughing out loud on the NYC subway while commuting, and having people move away from me <g>
. Here's an excerpt:
------------------------
I spent the next several days productively sitting around being nervous. Then, on the day before my colonoscopy, I began my preparation. In accordance with my instructions, I didn't eat any solid food that day; all I had was chicken broth, which is basically water, only with less flavor. Then, in the evening, I took the MoviPrep. You mix two packets of powder together in a one-liter plastic jug, then you fill it with lukewarm water. (For those unfamiliar with the metric system, a liter is about 32 gallons.) Then you have to drink the whole jug. This takes about an hour, because MoviPrep tastes -- and here I am being kind -- like a mixture of goat spit and urinal cleanser, with just a hint of lemon.
The instructions for MoviPrep, clearly written by somebody with a great sense of humor, state that after you drink it, ''a loose watery bowel movement may result.'' This is kind of like saying that after you jump off your roof, you may experience contact with the ground.
MoviPrep is a nuclear laxative. I don't want to be too graphic, here, but: Have you ever seen a space shuttle launch? This is pretty much the MoviPrep experience, with you as the shuttle. There are times when you wish the commode had a seat belt. You spend several hours pretty much confined to the bathroom, spurting violently. You eliminate everything. And then, when you figure you must be totally empty, you have to drink another liter of MoviPrep, at which point, as far as I can tell, your bowels travel into the future and start eliminating food that you have not even eaten yet.

Read more here...but definitely not after you've taken your prep solution, as the laughter will tend to create a spurting action...

you can find - you will thankful later on. 
I could not make it through drinking all of the laxative drink, it was positively horrid! I don't know if I will ever drink Sprite or 7 Up again.
The actual procedure isn't bad and you won't remember much. Recovery depends upon how much the anesthesia impacts you. Some people are really out of it and won't remember the conversations they have for the first few hours afterwards. I actually could have driven myself home (although they would not have allowed it). You are not supposed to drive that day. I had my procedure first thing and by 3pm I couldn't stand it any longer and was out running errands.
procedure is a piece of piss
Relevant part starts at the 1:30 mark.
"This wasn't an exam, this was a courtship, as far as I was concerned!"
"So I asked him if this was going to hurt. To which he responded, and I quote, 'You might experience a SLIGHT cramp', he said. Which is somewhat akin to telling somebody standing in the path of a tidal wave 'you might experience MOISTURE!'"
Damn, Dennis was funny as hell. He died entirely too young.
Hope it all came out OK, pal.
. . .if after awhile, you're shitting WATER instead of solid matter, you're doing it right. Don't stop - do the whole bottle. All of it.
The doctor will knock you out completely before the procedure. It lasts about an hour, but you won't know it or feel it.
However, PLEASE ensure that you have transportation by a friend or a relative both before and after the procedure. In fact, do NOT drive any type of vehicle afterwards for the rest of the day and night. Do not have ANY alcoholic beverages either during that time. It takes that amount of time for the anesthetic to wear off and flush out completely.
You can return to driving a vehicle the next day.
Hope this helps.
He's taking the truck to the appointment, dammit!
