by BRONSON PAGEIf anyone in your family has had colon cancer, take the age they were when they were diagnosed, subtract 10 years, and that’s the age at which you should have a colonoscopy. Mom was 50, and so being 40, I had my first colonoscopy this year, besides, all of my coolest friends (Paul, Jeb, Sonny) were having them, and I’m not one to be left out. Here’s how it went for me. If I can get through it, then anyone can:Thursday:Breakfast is the last meal I’ll have for over 24 hours. At 9AM, I had mixed fruit with yogurt, cottage cheese, and granola, and since I knew it would be a while until my next meal, I felt a rice krispy treat was also in order. An hour or so later, the hunger kicks in, and it has to be quelled with clear liquids only, and juices without pulp until Thursday night. I definitely felt the absence of solid food, and learned that when I get a specific gurgle on my left side, under my ribcage, it’s time for a game of iPhone Scrabble in the “throne room.” When I got home, Sam was having our favorite Chinese chicken salad, and I would have killed for even a taste of the Styrofoam container it was in.

Either way, it tastes like lemon-lime crystal lite made with sea water. Icy cold, or even on the rocks is better than room temperature because you’re going to be drinking a quarter-liter every fifteen minutes for an hour. It starts to work in about 20 minutes. If you live with others, for their sake, please crank up the tunes. At few points in one’s life are the ramifications of one’s dietary choices more apparent or the reasons for making resolutions more clear. We’ll leave it at that.
