Which solution did they give you? Was it the 1 gallon one?

When I had my colonoscopy I never did get clear stool, and all was fine. As long as you drank all the solution, you should be okay.

Don't worry too much about the colonoscopy, it was a piece of cake.

Good luck tomorrow.

Heck I couldn't even drink the whole gallon - there was still about half an inch left on the buttom that my stomach refused to let me drink. By the end the stool looked fairly clear and the next day it went fine (I did mention that I didn't drink all of it and even that was fine).

Note to anyone who's having this done in the future - if the nurse asks you if you want apple juice or orange juice afterwards - just say no!
I said yes to orange juice, and it made me feel really sick, by the time I got home I threw up and then I slept the whole day. After that I felt pretty good though.
