OOooh, I wish Ptree was here right now to answer your question! (she's in mexico lucky her)
You have been eating raw food for a couple of months now, haven't you? I imagine that, as ever, a good balance of cooked food and raw is the best. Remember the 80% alkaline diet and the 20% acid? (I bet you're doing amazingly well in that regards eh? red: EdgarCayce) I think it's probably the b&p backing you up....if you cut back, keep drinking lots of water....I'm sure your bowels will start moving again.
You were going to do the parasite cleanse anyway, right? I think it's fine...it just may get you going, as a side benefit!
