The answer to your question is: your going to get worse! You just can't take more metformin and think everything is ok?
If you can't be bothered...Who can? You really need to take this more serious then you seem to be. High sugars do damage to your organs, your insides and eyes, kidneys over time. You may not notice anything now but in time you will and then...the damage is done too late.
I hope you start doing what your Doc said to do and get some help with this if you find it too overwhelming. It's just a matter of making up your mind you want to stay healthy and so you make the changes you need to keep your sugar in tact.Best of luck!
