Hi, Jo .. Welcome!
I ditto Lois with congrats on the weight loss. Major accomplishment for you.
I had been told I was "borderline" for 30+ years before finally, 3 yrs ago, tipping over into full blown diabetes. Now the docs use the phrase "pre diabetes." I take that to mean if you don't get hold of your glucose numbers, then you're likely to slide into the disease with all the potential negative side effects.
Hopefully, if the doc said you could come off the meds, then you have managed some worthwhile control of your sugars. Perhaps you can maintain normal glucose levels over time, but that will mean you have to keep a continual check on yourself ... there's no going back. It's all about the numbers.
