That sucks. Had one last year. The prep is the worst part about having a colonoscopy. Hopefully this knowledge will be helpful in case you've never had one before. I know I was freaking out before mine, but it turned out to be not such a big deal.
I thought you already had it. I had my second colonoscopy last month. The prep is worst part. The procedure itself is not a big deal at all. You'll be fine. Have another popsicle or jello!
