I am confused on when to test my BG, when first diagnosed I was told to test before meals, having read some replies on here and in the monitor guide it seems most test 2 hours after a meal. Today I tested before breakfast and then 2hiurs after. Reading were 12 before and 22 two hours after. Is there a correct time to test. I am type 2 but some on here have advised to get checked again due to having reading in the twenties most days. Contacted DN have telephone appointment next week to discuss things.
