I'm now 63 and using Metformin, although I have tried and I know I can do without it. I like the slight freedom it gives me. I keep to a very low carb regime and have an Hba1c which is in the average range for a non-diabetic[5.1%] HOWEVER, I am NOT cured. If I were to eat a large plate of pasta, My BG would spike through the roof.
What I have done is that in 6 1/2 years since diagnosis, I have prevented any "progression"
I think control is possible, but cure unlikely.
If I were to become seriously ill with some kind of infection, my hard work would probably fly out the window. I'm struggling now to keep the numbers down and all I have is a cold.
