Basically, we all have different food tolerances. You are not yet sure of your own tolerances, since you say you haven't tried too many vegetables or fruits since takedown.  I'm not discouraging you from doing the cleanse, but considering that you don't know how you'll react, keep in mind that in general, eating a large amount of raw vegetables and fruits may cause excess gas and bloating. Generally, fibrous vegetables and fruits are harder to digest, and roughage heavy diets can increase the risk of obstructions for some of us, in cases where we have known issues such as stricture or adhesions. At the very least, you'll probably experience increased frequency and looser stools by eating only fruits and veggies, at least for the first few days until your system adjusts.

Just a few things to keep in mind.

I've done a lot of 24-72hr cleanses on nothing but fruits, fresh juices and veggie broths...they are very effective if you just want to clear out your system...I don't use them for any other reason...but I need to warn you...you will spend a great deal of time in the washroom...as a k poucher it is bearable but as a j poucher you may find that you need to sleep there! 

At the first sign of severe cramping, pain or any other unusual problems please stop...if you are not used to it then you need to look out for blockages or intestinal irritation...and if you are running like water, in spite of all of the fluids that you will be drinking, you may end up dehydrated (the whole point of the cleanse is to rid yoursel of toxins, which means salts... you could lose too much and end up hurting yourself so please take it slowly, be prudent and if you feel light headed, dizzy or sick to your stomach, stop, drink something salty (chicken broth?) and lay down.
