2 hours after main meal

As a Type 2 your 2 hr post prandial reading should be no more than 8.5 mmol/l. Lower is better !
Fasting(waking) should be between 4 - 7 mmol/l.

CJ, are you taking medication?
The highest level reached after eating is at between 45 and 75 minutes in most cases. 2 hours after, It is probably on its way down again. So if you are at 10 after 2 hours, It will probably have been well into double figures at its peak. You can investigate this by testing at 1 hour and then 2 for a few times.

I this is a Metformin 500? Your diet is the more significant part of your control. Even at maximum doses of 3 grams of Metformin, it cannot lower Bg by much, perhaps 1- 2 units.
When in relationship to your meals do you take the Metformin?
The recommendation is usually immediately after a meal. If only taking one per day, that would mean that ideally your main meal should be at pretty much the same time each day.
