I may be a weirdo...but I love having colonoscopys. The prep sucks, but its really not that big of a deal. But I feel so good when my body is like completely free of wastes.
Ditto with Kasper on the drugs, Im loopy all day afterwards lol.
Basically you drink this nasty stuff, or maybe your doctor is giving you the pills, but your going to crap your brains out until its like just water coming out, then when you go in they give you an IV, pump you full of drugs to make you all sleepy, then you wake up like nothing ever happened. Thats how mine go at least.
