Improving Tolerability of Bowel Preparation Laxative for Colonoscopy

Comparison of Patterns of Laxative Ingestion to Improve Bowel Preparation for Colonoscopy: A Pilot Randomized Trial

The purpose of this study is to determine whether the pattern of flavoring and drinking of laxatives for colonoscopy can improve the experience of patients when they are undergoing bowel preparation for the test.

Investigators hypothesize that patients will have a better experience if patients taste the bowel preparation laxative with and without flavoring and then decide how they want to drink the rest of the laxative since taste preferences vary widely from person to person.

Exclusion Criteria:
