Summary: For patients having colonoscopy in the afternoon, prep with one gallon of polyethylene glycol (PEG) the morning of the procedure appears to be associated with improved efficacy of bowel cleansing and less difficulty with loss of sleep or insomnia, but no difference in overall adenoma detection, compared to prep with one gallon of PEG the evening before.
