Summary

This study tests whether a 'thirst relief kit' containing a lemon popsicle can reduce thirst intensity in patients who have undergone bowel preparation for a colonoscopy. Participants are randomly assigned to receive either the popsicle or a placebo (a small amount of distilled water). The goal is to see if the popsicle improves thirst, dry mouth, and overall satisfaction during the hospital preparation period.

What this could lead to
