Well I bit the bullet on Friday and called the DN and got a batch of Merformin. My levels are good again, am back on track after a wobble but I will probably start taking them on Monday. Have you noticed it has made a major difference to your A1C test?
My home meter readings were lower after I had worked slowly up to the maximum dose of 2g Glucophage XR. (I took on board Dr B's recommendation that Glucoophage may be more effective than generic Metformin, and managed to persuade my GP to prescribe it, as nowadays Glucophage is not much dearer than the generic.) After a difficult 3 months with health problems and meds that appeared to raise my bg, my A1c at the beginning of January was 37. After starting Glucophage and 3 months of much better home readings, with fasting numbers throughout May never over 5 and more often 4.9, I had another A1c test at the beginning of June. I was confidently expecting eg 34, so I was shocked to get a rise to 38. I still don't understand why, except that my haemoglobin level was very slightly above normal,which may have skewed the test, but I would not have thought to that extent.
A1c 38 = an average of 6.4, but the days when I see a 6 on my meter are very rare.
This has not discouraged me from taking Glucophage. Since I have already cut carbs to the bone, all I can do now is try to increase the quantity and intensity of my exercise. I will have another A1c test at the end of July. Luckily for me, I have accepted the views of Dr Bernstein and Jenny Ruhl that post prandial readings are more important than A1c, but I'd dearly like to see a lower A1c too.
