I'm of the age where it's time to get one done. Dr already put in for it, I just have to schedule it. He gave 2 options, 1 a routine blood test & the other the more obvious route. I'm trying to wrap my head around the prep for the more invasive one. Don't know how i'm expected to physically work with the no food intake. Anyone have any more insight? Transportation is another, but that isn't the concern, the test is the priority. I like pooping in boxes. Tell me moAr!
