home made colonics?

i am also having a hard time with the b/p(stool gets harder)... and know many people who had big succsess with colonics. since i am here in costa rica, where its impossible for me to find a professional colon therapist, i was wondering what is the difference between enema and colonic. once i put a big water container, i can also use a lot of water, repeat it and so on. the only difference i see, is, that you have to take the nozzle in and out between water going in and out. is there any hidden secret, why i cant do it by myself? i allready did enemas with 2 liters in one go. if i repeat these some times it should be the same than a colonic.
all this cleansing, is it just about the colon, or also the small intestines? then offcourse the shakes make more sense...
i guess this issue has been answeres many times before, i just cant find it...

thank you, viraj Tweet
