If my doctors practice diabetic nurse takes me off Metformin because she thinks I've controlled my type 2 diabetes so well, am I still classed as being diabetic? I've gone from 95kg to 77kg in approx 18 months cut out all sugary drinks, sweets, cakes etc and my HbA1c has gone from 75 to 43. I'm worried that being taken off the Metformin I may go backwards. Does it help that much? Please advise.
