Study participants will be instructed to take nothing by mouth after midnight on the day of their colonoscopy. They will also be advised to avoid discussing the details of their bowel preparation with their endoscopist until after their colonoscopy. Upon arrival to their scheduled colonoscopy appointment and prior to their procedure, patients will be provided a short survey assessing their bowel preparation experience (please refer to appendix document Patient Survey for details). Also at the time of insertion of an intravenous catheter (which is required for all procedures) 5 cc of blood will be drawn for a complete metabolic panel and sent to the TUH laboratory to evaluate for electrolyte disturbances.
