Sorry might be slightly unrelated but I just came here to say that I have now had two colonoscopies without sedation and that's by far my recommendation. You are in and out in less than 20 min you only have very slight discomfort at the bends but nothing memorable and you don't have all the side effects of the sedation. Honestly I'm amazed that they even offer sedation for such a procedure! Good luck though I know it can be stressful
