Man, you totally just wrote my story. Diagnosed in May this year as Type 2, but "weird" (not obese, active, etc.). Went on metformin and low-carb, has worked wonders for my A1c, but doctors think I'm not Type 2. Just got antibody tests back as negative, with a "keep testing and see what happens" from my doctors.
Low-carb and working out is working for me now (my a1c is 5.1), but I also can't eat "normal" meals. Less than 20g carbs per meal is the only thing that works right now, and I've got some other weirdness (very low insulin production, etc.). I test three times a day, and know the signs of DKA and am under orders to go to the hospital with a high BG.
Other than that, I have no idea what to expect! Am I honeymooning? Am I just a weird Type 2 with minimal insulin production and resistance? Will I need to be on insulin?
