Metformin

I never heard of a Type 1 taking metformin. Not in this country.

They are researching metformin for both type 1 and for anti-aging now. (also anti-parkinsons which some call Type 3 diabetes)

Have they checked your c-peptides? If you don't take enough insulin for the food you eat eventually you will wind up with DKA which is life-threatening. Don't cut out insulin entirely, it will result in death unless you are producing enough insulin naturally (yes, it's possible, even for type 1s, to start producing insulin again. I have -- and yes, I have proof).

Myself and several others have shared our c-peptide test results over at our blog, CureType1.

I have two non-zero c-peptide results, 0.17 nmol / L and 0.107 nmol / L, but other type 1s there have reached much higher values, like 3X my amount (peak insulin production during OGTT roughly as good as the fasting levels non-diabetic person).

The only reason I don't have more data points is because it's next to impossible to convince endos or GPs here in Canada to run a c-peptide test as someone who has had type 1 diabetes for 24 years. They look at you like you're crazy to even suggest tracking it, even though I've proven, twice, that I am producing insulin again. And this isn't big news, many type 1 people are in fact producing small-ish amounts of insulin, it's just far from good enough to make it to the news. However it is my belief that tracking it closely, or perhaps tracking HOMA values (using blood serum glucose values combined with endogenous insulin values one can estimate beta cell function, it's an alternative to a c-peptide test, and something that researchers are working on a home beta cell function test -- a few years off still, as of yesterday's conversation I had with the scientist involved).
