You need to run things based on your meter. This will dictate med regime as well as the foods you eat. You need to check your fasting number as well as 2 hours after eating. Fasting should be less than 5.5 and 2 hours post should be less than 7.8.
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!
I've been able to avoid any diabetic meds or Insulin through demanding physical exercise and a very healthy, low calorie, low carb balanced diet. Not only does my diet and exercise help to keep my blood sugar and blood pressure at a very healthy level all the time, it also makes me feel very healthy and have more energy!
In addition to my balanced, healthy diet, I also do snacks, but I "chew but do not swallow" the snacks.
I used to know a guy who treated his diabetes much like the OP. He got a small cut on his foot. Months later, after much pain and time in the hospital, he lost his foot. Then most of his leg. Then he lost his other foot due to a minor injury. Last summer he lost his life.
