oh pluggy, i hope you're feeling better since you wrote this first post!
i've had plug problems too, mostly from experimenting with many different dietary programs, i got my body so confused and sensitive!
the thing that has worked for me, after getting real-life, in-person testimonials from a few people i know... is dr. Richard Schulze intestinal formula #1. it has been wonderful! one capsule at night with dinner, or just after, usually does the trick. sometimes 2 are needed if i'm really out of whack.
that and a clean & healthy Diet vegan diet. lots of veggies, fruits, primarily raw foods, occasional whole grains & beans (all full of fiber!). i've recently returned to this dietary lifestyle after a few years of experimentation with some of the "new and improved" fad diets. duh! for me personally, i wish i had remained with my initial instincts (was whole foods vegan for 7 years before all this experimentation)! i never had poop problems until i started messing around with the food intake.
if you want to get more info on Dr. Schulze you can call 1-800-HERBDOC. they'll send you a catalogue, which in itself is a wealth of info!
