Hi this is a little complicated. I have been scheduled for a colonoscopy for tomorrow. I was given a script for a preparation that was not covered by my health insurance so it was changed to PEG3350. I inadvertently discarded the preparation instructions for the PEG3350 AND kept the instructions for the first prep I received. It said I could eat vanilla yogurt and at 6pm begin drinking the solution for my test. Now I'm concerned that eating the yogurt (16oz) may create a problem since the instructions were for the other prep. It was organic yogurt and very watery not thick and creamy like most brands. I have not eaten anything else for the day and will begin drinking the PEG prep in 2 1/2 hours. Will it be ok
