Tips for a Successful Colon Prep

• Plan on each dose taking several hours.

• Stay near a bathroom. Stock up on soft toilet paper and reading materials.

• If you don’t like the taste of the prep, you may add yellow lemonade Crystal Light® to the mixture. We suggest mixing it into 1 glass at a time.

• Drinking the prep through a straw may help improve the taste.

• Between glasses, you can chew gum or suck on slices of lime or lemon or hard candies. Avoid red or purple candy.

• After you mix the prep, we suggest you put it in the fridge. Take it out of the fridge at least 2 hours before you start drinking it, so you won’t feel too cold.

• If you get chilled, try putting a blanket in the dryer to warm it up before using.
