I am on insulin but I want to switch back to metformin, My doctor said I could but I have to get a blood test first to make sure my kidneys are alright, I have Diabetes 2 and my doctor told me if I lost so much weight and started eating right and excersing I could be diabetic free, I dont follow my 45 carb diet like I should and I pretty much eat what I want, I am never going to get better that way, I have come along ways to eating healthier though, I know a couple people right now that had diabetes 2 and dont have it any more, The one makes sure she excersizes every day with out fail for a half hour and the other one was doing yoga and lost weight and neither one of them take medicine any more, I am grateful that I am not diabetic 1 then I dont think you can ever be freed, I would never stop my medicine I know how serious that could be, I am diabetes educated
