@howardm I am not familiar with the Libre system, I test using a regular monitor. My A1c is always relatively low, often under 5, the last test, about a month ago, it was 5.6 so my endocrinologist does not insist that I test daily.
He has told me to test at different times of the day, after different meals though. I was always testing after breakfast. I think it does make more sense to test after different meals because it can change greatly depending on what you eat. I almost always have oatmeal for breakfast and later in the day, my meals tend to have fewer carbs.
Sometimes I wonder if I really am still diabetic but my endocrinologist has said once you have it you are always considered to be diabetic.
