As a patient myself, I was stopped by my GP from testing myself about 2 years ago, and since then I have not self tested ever.
At the time I stopped testing, I had reduced my HBA1C from 9.4 initial diagnosis down to 6.8 to 7.1 range using only Metformin and diet as my glyceamic control. Since then my HBA1c has ranged from 7.8 to 8.6, and is slowly rising. My medication now comprises 1500 mg Metformin, with Pioglipizide and a glicizide added to the regime.
When I was testing, I did experiments on my food intake, and determined that I was not severely affected by grains or pulses or potatoes, i.e. starch, but was extremely sensitive to monosodium glutamate and dairy products. That was how I reduced my BGL level using diet, and it worked.
When my doctor told me to stop, I lost heart in controlling my disease, and went on 'holiday' with my diet. So now I am almost back where I started.
I think that self testing is very important, and can make significant difference to the outcome. It is not suitable for all, but some of us would like to use this technique to experiment with our disease management, and act proactively.
For my own edification, I discovered that chromium, zinc, and vitamin B1 added to my diet were benficial. I discovered that cinnamon, selenium, Omega 3, and some other quack remedies being touted on the web did nothing for me except empty my pocket. I was about to start investigating CQ10 enzymes, but the doctor stopped that trial in its tracks.
Although I did try recently to enquire about starting self testing again, I was told quite categorically that the PCT only supports those on insulin. Since test strips are not available OTC, I am unable to even contemplate it.
