Colonoscopy

I usually start eating lightly a day or 2 before prep day just to have less "stuff" to flush out and then follow the directions from the doc. Other than that no special diet should be necessary. Stop solids on prep day.

A suggestion: Don't guzzle whatever prep you are using. Sip at it within the time frame you are given. You can get sick if you guzzle it. ~speaking from experience sadly~

I start eating lightly a week to two weeks before the colonoscopy. I also do not use the Gatorade for the prep. I use white grape juice. Much better.
