I'm getting an upper endoscopy and a colonoscopy. what are your experiences if you have had these procedues?

Don't worry much. The doctor and nurses will take care of you. You would not even feel a thing. I had a colonoscopy last month. The only worst part is before one day to have the procedure - that is you have to cleanse your stomach and go to the bathroom every minute. You probably have by now the instructions. Just follow the directions and you will be fine. Do not eat anything 1 day before the procedure. Is just a piece of cake. Believe me! It' s painless they'll give you "anxiety medicine" what my nurse said to me.
