Not cured I'm afraid, just need little amount of insulin! But you still in honeymoon period!
A couple things going on here..
When you first diagnosed, the pancreas is still producing some insulin, but not enough to do it's job probably, so high Blood glucose levels, but high blood glucose levels are insulin resistant... So initial insulin dose, will be higher to combat the insulin resistance and bring levels back to normal range.. But as the blood glucose start getting the near to the normal range the resistance lowers and you need less insulin to do the same job..
During the honeymoon period, because the body is know being supported by injected insulin, the pancreas doesn't have to work extra hard to produce insulin with a decreasing ability, so can ease off... This can actually restore some of the pancreas function. So it isn't unheard off when a newly diagnosed T1 diabetic, after the initial introduction of insulin, to reduce to very small amounts and in the odd case actually need to stop injecting insulin for a short period of time...
You generally know that you are coming out of the honeymoon period, as blood glucose normally goes up and becomes unstable as you start taking over more of the pancreas function with the injected insulin and your ability to adjust dose to your needs really starts showing..
But our body does change over the years, and how we control and tactics use also changes, as we adapt as we go...
