I have been diagnosed a diabetic now for about 6 years or so. I have been on the metformin for about 5 of those years. The first year I controlled the blood sugars by diet and exercise only. Later I got more lax with the diet & exercise and got put on the metformin. As time passed I got increased to 750mg twice a day. I started felling nausea more and more and then have that feeling every day all day long. Went off it totally because it was so hard to function when you felt sick all the time. The nausea went away. Now I am taking 500mg every other day. This is not working either and still have nausea from time to time. I am running 180 to 190mg/dl. I think if I could take the 500 every day I would be able to control the numbers. My question is, is there anything to take to keep the nausea under control?
