Acceptance of health treatment claims that are not adequately supported by evidence. I dislike it when people sell ineffective and even harmful alternative health products to exploit the desperation of people with chronic illness.
Not sure you would qualify for a CGM because they are restricted t those who need them the most, such as T1s who need a hypo alarm to wake them up in the night to correct it with glucose.
But in any case, we can probably help with the unexpected readings. What sort of foods do you eat, and what type of insulin are you on? What was your latest HbA1c result? Are you on any other meds?
