I'm going to be having a colonoscopy, and I want to know what to expect. What should I do to prepare?

1.  Make sure you have plenty of fiber in your diet, as this will help you pass the scope more easily.
2.  Drink lots of water before your procedure.
3.  Avoid eating anything solid for at least 8 hours prior to your appointment.
4.  Talk to your doctor about any medications you are taking that could affect how well you pass the scope.
