I ask this as I have been testing regularly for a month or so. My readings are coming down and my medication I have reduced to 2 tablets. I test before my main meal and 2 hours after and my readings normally stop the same or go 1.5/2 higher. I got a fright the other day when testing after the meal and got a reading of 11.4 from 5 before the meal. I tested again straight away and my level was 6.2. I tested again with a different monitor that reading was 6.3. Testing again with my monitor the test showed 6.2 again hence my question can these monitors be trusted.
