So now I am wondering.. I am type 2.. diagnosed with pre-diabetes about 3 years ago. At diagnosis the a1c was 6.2, one fasting above 126 and one below. Diabetes is never "mild" but the reality is type 2 runs in the family so by the time I was in my 50's I expected this to eventually happen. I test before I drink any alsohol and if I am on the low side I don't drink anything unless I eat with it because I notice it will drop the bg level. I will have 2 glasses of wine (mostly with food) and it does not effect morning readings. Those are between 85- and 105. So my totally unscientific conclusion..
There is insulin running in the system, I take 15mg of actos which makes the insulin more efficient (counter-acting insulin resistance) and the effect is much more based on the carbs I eat rather than the 2 glasses of wine. Every one is diffent.. just stating what I have observed for me.
