My A1c , last Friday , was 14.9. That's two A1c's in row where it was high. Doctor put me on insulin shots( Lantus SoloSTAR), supplemented with my Metformin. I started with 10mgs. 7 days later, I'm up to 30mgs......and no change in glucose level?. It remains at around 14. How much insulin can a person take before finding the right dose?
