Confused by Reading

all of those are good readings
not all will advise taking a 1 hour post meal reading but it is a good way to learn what foods do to your blood sugar.
your pre meal of 4.5 is excellent and 2 hours post meal is pretty darn good too.

With himtoo on this good control the numbers are in the same ballpark as I would expect to see on a good day.

For me I find with a lowish carb meal the peak blood glucose occurs about 75 to 90 minutes after a meal then falls quite sharply, then after about 2.5 hours the rate of reduction in glucose levels slows down.
