Depends on the surgery, I suppose. I've been in the non-diabetic range for two years, and my check-ups have been reduced to once every 6 months rather than every 3 months. I suppose if I want I can reduce to once a year, but I'd rather keep things a little more regular, myself. You've done really well, but most surgeries want to keep an eye on you once you're diagnosed, and that's in all honesty, a good thing. I know it's inconvenient sometimes, but T2 isn't just "gone" when your numbers are improving. You're still diabetic, even with non-diabetic numbers. You have to keep them in check, and having regular tests, including for co-morbidities (like high bloodpressure, kidney faillure and non-alcoholic fatty liver disease), is the wise thing to do.
As for reducing meds, it's certainly something you can discuss with your GP.
