Well... about to start prep for my colonoscopy tomorrow.
Kinda worried AF going into it.
If you never hear from me again, it's because I died while being roto-rooted.
At least my liver made a full recovery...
Gentlemen.
I find the prep to be worse than the actual procedure. Assuming a good anesthetist that is.
I second that. I did one recently enough and it was not a problem at all. Sedative plus the twilight anesthesia thing and you won't notice a thing.
My prep was 50 grams of Mannite dissolved in half a gallon of water to drink. Be aware that i suffer from Fructose Malabsorption, so it worked very well. But the nausea afterwards was horrible, lasting for about two hours, not to speak about the other side effects. That was all, i refused any sedative and laxatives, like every other real man

By the way, @Antisthenes, real men are able to do things that normal men are afraid of. So feel free to go on with your teenage homophobic issues
