Margie, are you still on metformin with the Lantus? You of course are THIN (I need a green face for envy

), so it might not be any insulin resistance affecting your insulin needs ... or it STILL could be ... but that is not a huge dose of Lantus, either.
Ti Jae, I do appreciate you chiming in here, since you were DKA, you too have KPD -- ketosis prone diabetes, and it is possible you, like I have got beta-cell insufficiency as well as IR ... some diagnosticians by the way categorize T2 = non-insulin dependence; T1 = insulin dependence or NO insulin secretion. It it a very loose definition.
Please keep us posted on how you do without insulin! It does take about 6 months for beta cells to rebound after a DKA episode, according to one study Mike (Rekarb) posted somewhere in the T1.5 forums ... it sounds to me like your endo followed the protocol I wished MY Endo had followed ... better for your betas. I now see his partner and suspect she would have discharged me on insulin.
have you had antibody testing at all?
