I agree with these other posts that no one should just STOP taking meds. Obviously, you know this and wouldn't be foolish in that regard. However, that aside, have you researched the role of parasites in the cause of diabetes? Have you explored the Hulda Clark books and protocols? I don't want to be insulting, because I'm sure that you've been diligent, but sometimes there's still some great piece of news/advice/help out there that we haven't laid hold of, so I just wanted to bring this up! :)
Here's what Hulda Clark says (see link at top of curezone page, if you haven't already):
Diabetes Can be Cured
All diabetics have a common fluke parasite, Eurytrema pancreaticum, the pancreatic fluke of cattle, in their own pancreas. It seems likely that we get it from cattle, repeatedly, by eating their meat or dairy products in a raw state. It is not hard to kill with a zapper but because of its infective stages in our food supply we can immediately be reinfected.
Eurytrema will not settle and multiply in our pancreas without the presence of wood alcohol (methanol). Methanol pollution pervades our food supply -- it is found in processed food including bottled water, artificial sweetener, soda pop, baby formula and powdered drinks of all kinds including health food varieties. I presume wood alcohol is used to wash equipment used in manufacturing. If your child has diabetes, use nothing out of a can, package or bottle except regular milk, and no processed foods.
By killing this parasite and removing wood alcohol from the diet, the need for insulin can be cut in half in three weeks (or sooner!).
Be vigilant with your blood sugar checks. The pancreas with its tiny islets that produce insulin recovers very quickly. Even if 90% of them were destroyed, requiring daily insulin shots, half of them can recover or regenerate so insulin is no longer necessary. The insulin shot itself may be polluted with wood alcohol (this is an especially cruel irony -- the treatment itself is worsening the condition). Test it yourself, using the wood alcohol in automotive fluids (windshield washer) or from a a pint store, as a test substance. Try different brands of insulin until you find one that is free of methanol.
Artificial sweeteners are polluted with wood alcohol! Instead of helping you cope with your diabetes, they are actually promoting it! Do not use them.
Drugs that stimulate the pancreas to make more insulin may also carry solvent pollution; test them for wood alcohol and switch brands and bottles until you find a pure one. You may not need them much longer, so the extra expense now may soon reward you.
Many persons can detoxify the amount of wood alcohol that pollutes our foods. They do not have a mold, Kojic acid, built up in their bodies as diabetics do. I have found Kojic acid in coffee, and potatoes with gray areas inside. Do not eat discolored potatoes or peels, even if cooked or baked. Being able to detoxify a poisonous substance like wood alcohol should not give us the justification for consuming it. All poisons are bad for us. Do not consume them.
All diabetic persons also carry a virus, HA virus in the pancreas. This virus is grown in the skin as a wart but is spread quite widely in the body such as in the spleen or liver besides pancreas. It is not necessary to kill the virus since it disappears when the pancreatic fluke is gone. The HA virus undoubtedly belongs to the pancreatic fluke. The question can be asked: Does the fluke or its virus cause diabetes? There might even be a bacterium, so far missed in our observations, that is the real perpetrator.
While recovering from diabetes it is very important to check your blood sugar every day. Improvement is so rapid, you may suddenly be over-insulinized by your next shot. Cut down your dose to suit your actual need.
