Dawn phenomenon plays a big part in my morning bg reading. Today at 6:50 I was 5.6 - down from 5.9 when I went to bed. Then by 7:20 (still well before breakfast) I was at 9.2.
My fasting blood glucose always rockets first thing. Before evening meal it is usually between 5 and 7 but I suffer from a serious case of dawn phenomenon.
So today at 6:50 my bg was 5.2 but by 7:20 it was 9.4 and all before breakfast
