Brief summary
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.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall patients' experience with the bowel preparation process with ratings from 1 (unbearable) to 10 (Pleasant) | At the time of colonoscopy | On the day of the patient's colonoscopy, each patient will complete another form regarding their bowel preparation experience. Information gathered will include their ratings of the bowel preparation laxative's taste, ease of consumption, presence or absence of nausea, vomiting, whether they consumed the entire recommended laxative and their overall ratings of the bowel preparation experience. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Endoscopist ratings of the patient's bowel preparation quality using Aronchick scale | At the colonoscopy | During the colonoscopy, the endoscopist who will be masked to the assignment of the patients will assess the quality of bowel preparation and grade as Poor/Inadequate, Fair, Good, Very Good or Excellent. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Prevalence of colorectal neoplasia (polyps, adenoma and cancer) | At the colonoscopy | The detection of colorectal lesions during colonoscopy (polyps, adenoma and cancer) |
| Correlation of beverage intake patterns with tolerability of bowel laxatives | At the time of colonoscopy | Investigators will examine patients' preferred pattern of non-alcoholic beverage intake for coffee, tea and carbonated drinks with their bowel preparation experience |
