"I've had to drink suprep bowel prep kit 5 times . 3 of them because I'm have bowel problems and they are using it to help me go. The other 2 kits are for a colonoscopy and an endoscopy. 2 days before the test I started a bland diet. No meat nothing grease, no bread.etc. 1st prep after a breakfast lunch and dinner of clear liquid I drink it. I took big drinks of the prep followed by some apple juice.
