I've had the unpleasant experience of a "flexible sigmoidoscopy". A shorter look up the guts. Same prep no drugs. Wide awake. Hurt like hell. Told that doc when it was over that he would never see my ass or any other part of me again. Money grubbing fugga.
That was in the early 90's, done 5 colonoscopy's since then. They cut out polyps every time, nothing cancerous yet.
If I have the choice I get the prescription foul tasting sea water prep over the stuff you just buy otc. The otc stuff keeps me awake all night with the urge to chit some more where the prescription stuff is all over with about 10:00 and I can sleep some before the procedure.
My father had colon cancer, I'll gladly do the screening/polyp nipping.
