Hi, I came down with a stomach virus Monday Evening. The vomiting subsided after a few hours but the diahrea lasted until yesterday morning. I am still weak, but have eaten three meals today and tried to hydrate with mostly clear liquids. I am scheduled for a colonoscopy Monday morning and the prep is suppose to start now with a Dulcolax tablet, another at noon tomorrow and then the Miralax with 64 oz of Gatorade tomorrow evening. Tomorrow is a liquid diet day. I had a flu vaccine yesterday also. Will it be safe to do all this prep after several days of loss of so much fluid?
