Hmmm. That sounds like a job for a pro. Have you tried to catch Andreas Moritz or the Barefoot Herbalist? I would say that the simplest start in cleansing would be the P&B shakes. They don't raise blood Sugar and can help you eliminate waste build up and toxins. Of course, the Water Cure is believed to have a positive effect on diabetes, but that may only apply to early onset, not established diabetes. I'd say P&B is the way to go. Simple, cheap, and non-insulin/glucose affecting. Also, as long as you can go a couple of hours without eating without a reaction, you should be able to fit a shake or two into your day (P&B shakes require no food 1 hour before or after). I hope you find a save way to do it.
Hey, also check with the Colonix, Dr. Natura's, people. I've heard people have really great success with this system and it can be used for parasites and colon cleanses. I was even reading today that a woman was expelling liver/ Gallstones within 2 weeks on the program. She didn't know what they were, but fresh off my flush I was all too aware.
