Tips for a Successful Colon Prep
ξ Plan on each dose taking several hours.
ξ Stay near a bathroom. Stock up on soft toilet paper and reading materials.
ξ If you don’t like the taste of the prep, you may add yellow lemonade Crystal Light to the
mixture. We recommend mixing it into 1 glass at a time.
ξ Drinking the prep through a straw may help minimize the taste for you.
ξ Between glasses, you can chew gum or suck on slices of lime or lemon or hard candies
(avoid red or purple candy, as these can stain your colon).
ξ After you mix the prep, we suggest you put it in the refrigerator. Take it out of the
refrigerator at least 2 hours before you start drinking it, so you won’t feel too cold.
ξ If you get chilled, try putting a blanket in the dryer to warm it up before using.
