@Diabetic Frog I think many of us have been assuming you are not on insulin but being quite a long term Type 2 diabetic I wonder if we misunderstood your situation especially as you mention carrying jelly babies and your test kit. If you are on insulin then you should be aware of carbs and cautious of lowering them, especially if you are on fixed doses of insulin and clearly from the messages on this post you are not carb counting, so the best advice as always is to be guided by your meter.
I would also wonder if ....
a) You are really Type 2, then with a low carb rather than just low sugar diet, you might be able to push your diabetes into remission and possibly come off whatever medication you are taking
OR
b) You might be a misdiagnosed slow onset Type 1 (LADA) if you are on insulin.
I am sure many more people must have been misdiagnosed 18 yrs ago than are now, purely based on their age, since most doctors believe Type 1 is a childhood condition and more so back then. When people say a parent is/was Type 2 on insulin so they were doomed to get it anyway, I wonder how many of those parents may have been misdiagnosed Type 1s and how many are actually Type 2 but with the right dietary/lifestyle advice could have been prevented from needing insulin.
@Diabetic Frog
Would you like to tell us the story of how you came to be diagnosed and what medication you are actually on for it, so that we can understand your situation better?
