From eating to bowel prep

My home packet says to eat breakfast then at around 12pm take the bowl prep. About how many hours should I wait before taking the bowel prep stuff. I ask this because breakfast time could be 6am-7am-8am-9am. What do you guys think?

 I had breakfast that morning around 10, then I ate lunch as the packet said, a bowl of soup around 1 pm.  Started the bowel prep when I got home around 2 pm.  I had no problems at all.

   its up to you!  I suggest eating light meals for breakfast and lunch, Bowel prep around 2- 3:00 Remember what goes in - has to come out and you dont want to do it too late in day! you will be up all night ...

I mixed just a little 7-up / sprite  and drank it very cold - went down pretty good .
