I agree with everyone else that you have made great progress - well done! However I hope you will not be content to remain in the pre-diabetic category, as it is not as harmless as you think. Here is an extract from an article by the much respected author Jenny Ruhl:
"Prediabetes, even when it does not progress to full-fledged diabetes, is not a benign condition. It
does damage the body, and though this damage is often subtle--it causes small changes in the growth of blood vessels in the retina and kidneys, for example--the real danger lurking for people with prediabetes is heart disease. The risk of heart attack is much higher in people with prediabetic blood sugars than in those with normal blood sugars.
So if you have been diagnosed with prediabetes you should do all you can to lower your blood sugars to normal, since it is the blood sugars, not the insulin resistance that damage your organs.
The research makes it clear that what correlates most strongly with the risk of heart attack is how high your blood sugar goes
after meals, not the fasting blood sugars which are, all too often, the only sugars doctors tell you to measure.
People whose blood sugars are over 155 mg/dl (8.6 mmol/L) an hour after eating have a higher risk for heart disease. (Details
HERE.)
The experience of the online diabetes community suggests that if you keep your blood sugars under this level--many of us shoot for under 140 mg/dl (7.7 mmol/L) to be safe--you will do fine, no matter what your diagnosis, or even what the cause is of your diabetes. It appears to be the high concentrations of glucose in the blood that cause organ damage, not the underlying condition.
So use the simple strategy you'll find explained

The cheap, generic drug, Metformin is also highly recommended for people who are insulin resistant. It seems to block the process by which the liver deposits more liver fat, changes the way that muscles burn glucose to one that lowers insulin resistance, and lowers blood sugar.
Metformin's only significant side effects, observed after decades of use, appear to be that it decreases your chance of having a heart attack and also lowers your risk of developing various cancers. (Details
HERE.) If only other drugs had those kinds of side effects!"
You will see that she advocates taking Metformin. You have not mentioned if the extended release form is suiting you better.
