Just do it! Man up! The prep isn't a lot of fun,but neither is cancer! Just stay close to the porcelain throne the night before.
The procedure itself is a nonevent. They roll you into the room, the doctor says hello. I told him that I was there for a colon screening, and to not cut off any big pieces. He 'fine, let's get started'.
Then I woke up in the recovery room, high as kite. They give you that Michael Jackson drug. I've never used recreational drugs, so that was a new experience for me.
It takes a few minutes to come down from the high. The doc comes in says something like 'I trimmed a few polyps, nothing really scary looking, we'll call you with the lab results'.
I had my spouse drive me from the clinic to iHop, because I was pretty hungry. You don't want to drive yourself for a few hours, you'll still feel the drugs a bit for a while.
A week latter his nurse calls, says 'you colon is fine, come back in five years'. It's good to be told you don't have cancer.
