a colonic question.

hello all,

i am three weeks into a 1 month colon cleanse- detox. i have gotten a 4 colonics this month, and i have my 5th and final one next week. my therapist and i both agree that i am not releasing much. i have been eating 100% raw, P B shakes 2 x daily, did a 3 juice fast, drinking tons of water....where is my MP during my sessions? Or at least my stools in general? I haven't been releasing much on my own either lately. Any suggestions? Thanks in advance.
