What happens if i drink a small amount of water 2 1/2 hours before i get a colonoscopy?

This would likely be fine-you can take a small amount of water to take your medicines before any procedure, including a colonoscopy. Take the minimum amount of water needed to take the medicine. Good luck to you!

You should be fine, but you should get the nurses know when you check in for your procedure when the last amount of liquid that you drink was. It will likely be permitted. Good luck.
