It's been over an hour since it took my first dose of Suprep Drank the two 16 ounces water as directed Ive tried a little while ago to drink more water but cant My colonoscopy is tomorrow at 1pm. So far nothing has happened The only thing that's happened is I have the chills. When is this going to take effect and I start going? What if I never go? I don't want to do this again
