occurs at the tissue level... insulin fails to enable glucose. It doesn't matter if
you inject or use your own.

Research is looking for the causes of the failure at the cell membrane level.
They think it is an inflammatory cytokine made by fat cells.

Studies like you are doing worry me. Instead of sensitizing the insulin you do have to work normally, they just give you MORE insulin?

Metformin, chromium supplements, R-lipoic acid all help insulin work at the cellular level better.

Studies have shown that by the time a person reaches Type II diabetes, 1/2 of their pancreas insulin is gone. I can see using "some" insulin daily when diabetes results, but the dose you are on, is really high for a NON diabetic.

The liver makes more glucose when it senses low blood sugar. That is called gluconeogenesis...and you might be doing that metabolically to account for all that insulin. Drugs like metformin are handy because they shut that down somewhat to lower blood sugar.

I think you should read up on the internet:
topics like this:
Syndrome X (diet suggestions)- Also called metabolic syndrome
Metformin use in insulin resistance

Your health should come first, not some study. That's just my opinion.
