Yep, ask for it to be reviewed. Your morning reading may be more affected from your dinner too - I used to test ok at dinner if I had say something like pizza that I shouldn't have and my night reading ws fine but the morning one affected.
Pasta etc is a slow releasing carbohydrate so your levels rise progressively. If you were to check say 2 then 4 hours after eating, you would probably find your levels higher at the 4 hours!

But from the mother of a type 1 diabetic and researcher into diabetes in general, I am pretty confident you don't have GD!!!
