Bubs, I am a type 1 diabetic and I had high morning sugars from the off.
2 points, I find that ANY carb related snack between evening meal and bed over and above 1 or 2 biscuits gives me high sugars. Mine appear to climb from 6am to 10am when  having a lie in at weekends from 5.9 to maybe 7.6 (Used to go to 9.1 at times). When I cut evening snacks with too many carbs the readings reduce.
A point about meals, I cook virtually fat free but have shop bought oven meals occasionally. I think they are shot through with **** that sends your blood sugar up so the point made about shop bought potato salad as opposed to your home made variety is important.
Also, some people apparently get a "Break glass in emergency" response from their own bodies if their sugars go low at night. The alpha cell bit of your pancreas shoves glucogen into your systemn to raid more glucose from your liver in response to going low in the night. You could check your sugars at night but personally, I can never be ***** , prefer limiting any food consumption after about 8pm unless I get a low pre bed reading.
Hope this may help.
