I pour it out in a shot glass...an ounce and a half doesn't seem all that bad. I usually throw it down with one big gulp....gag......and then swallow 8 ounces of water. Then I go with ginger ale or seven up for the rest of the evening. When the time comes for the second dose.....I repeat the procedure after talking to myself to just get 'er done! My first colonoscopy was just the Go-Litely routine. That was truly awful. Then I had to repeat it two weeks later as a prep for my colon surgery. All things considered, it's a small price that we need to pay for piece of mind and in my case, to save my life. I wish your niece well.
