Samuel, that's great news! You deserve a lot of kudos, and should be very proud.
If the approach you are taking works for you, and you aren't feeling compromised in your quality of life significantly, you've found the right treatment protocol for you.
It is critically important, though, that anyone following this sort of regimen not be misled into believing it is a cure of any sort. It is simply a treatment modality.
It is no more a cure than someone with milk allergies avoiding all dairy products being cured of their allergy. They still every bit as allergic, they're simply modifying their life to manage it.
Same with treating diabetes, successfully, with diet, exercise, and lifestyle changes. For some people, these changes don't amount to restrictions for them, as they are already fairly compatible with what they like to do already.
Yet, they are still a T2 diabetic, just as much, for the rest of their life. In fact, there are many of us that would claim they are actually progressing their disease faster than if they were to go on exogenous insulin treatment (in addition to the already excellent diet/exercise efforts), because their still stressing their beta cells 24/7 for basal insulin and food.
The mistake made so often is the idea that achieving good BG profiles constitutes a "cure" or that "everything's normal" is just so wrong -- dangerously so.
When you have a 95 in the morning, that's great! But have you thought about what your body's doing to get there? With T2, your pancreas is still having to pump out enormous amounts of insulin, many times more than a non-diabetic. It's just that your beta cells, as they currently are, are up to the task.
The fact that you have to make any accomodations in your life to control your BG demonstrates that you've already reached the point where some cellular exhaustion, degradation, and possibly cell death has already occurred. This is because of your insulin resistance.
And that resistance doesn't go away with modified diet/exercise, and controlled BG. It is a treatment for the problem, and masks the underlying pathology. But it doesn't go away.
With exogenous insulin, you take the pressure off your pancreas. Beta cell exhaustion is a widely held hypothesis with some experimental backing. I believe I've seen this in action in my own experience with insulin treatment: Over 3 months since I started, I've seen my need for exogenous insulin decrease, my sensitivity apparently increase a little, and most interesting, the cieling for my highs when I go off the reservation drop considerably (implying the pancreas can now step in and juice up better than before, because it's resting most of the time -- I'm supply my basal and meal needs exogenously).
The first month I was treating myself with MDI, BG under tight control, if I pigged out on a bunch of carbs without bolus precision my BG would shoot up to 300.
Now, almost 4 months later, I can eat like Fat Lady at the circus, forget to bolus for it (that's what happened last night), and never go above 180-200.
I attribute this to a happier, healthier, pancreas. I'm just as insulin resistant as before (my carb ratio's been the same for 6+ weeks). So it's gotta be insulin coming from somewhere.
Long, long post. Important though, in my view. While you have been able to control your BG without oral meds or insulin, in my opinion you're doing more damage that way than if you were using insulin. It's ironic, but clinical results with diabetics seems to be supporting that theory more and more.
