If your A1c was at 75 you are a diabetic. It is awesome that you have managed to bring it under control and that is what we are all trying to do here, but you are still diabetic. No one can tell you whether to take meds or not, nor can we tell you what exactly will happen if you go off them as we are all different, but whatever you choose, you are still diabetic. This is for life. You will have to continue watching your diet for the rest of your life or those numbers will start to creep up while you are not looking. The good news is that you obviously know how to stop this. Congrats on that great number.
