Do you chug or sip colonoscopy prep?

It's generally better to sip or drink in small, regular amounts (like 8 oz every 10-15 mins) rather than chugging, using a straw and keeping it cold to make it more tolerable and reduce nausea, often splitting the dose (split-dose prep) into evening and morning servings as recommended by doctors for effective cleaning.
