Our family gave up boxed cereal a long time ago because of the sugar content. I make my own granola because everything in he store is high carb with sugar. I get hungry in the night as well but learned years ago that a scoop of peanut butter, no sugar, does the trick. The rise and fall is different for people, as my son takes Metformin at different times than I do. I wouldn't bother to check blood sugar in the night if it is no higher than 154. My neurologist has me taking 2 Metformin after dinner and then my blood sugar is close to 100 in the morning if I have worked hard sometime during the previous day. But that is my body pattern, My son spreads his Metformin out during the day. He also eats more fruit than I do, and more carbs. My best advice is to count the carb servings, with 15 grams being one serving. You can teach yourself to cut the number of servings per day. Balancing the diet is good for overall success.
Understand that the blood sugar levels go up for two hours after eating, and then drop, and then start to rise again. Exercise is part of the game, and affects the rise and fall as well. A glass of milk in the evening makes me sleepy and helps me avoid hunger at night if I didn't eat a large dinner. I was taught to be concerned only if and when the numbers go over 200 regularly. High carb snacks without fat and or protein can spike the numbers. You have to learn your body pattern of rising and falling, and the middle of the night is no time to be working on it. We need our sleep and we need to decide how much to eat before we eat it, Eating in the middle of the night is for the purpose of easing the hunger and getting back to sleep. You have to figure out what is the right amount of food for you during the day, and then the nighttime will take care of itself. I have never checked my blood sugar in the middle of the night, as it should lower by morning. I just know I never want low blood sugar again, as that is frightening. I suspect everyone is a little different in their patterns. Dorisena

Hi @loaks An official Welcome to Connect and on posting your first post. You'll notice that I moved your message to this related discussion called "How can I get my sugar levels below 100?" Where other members are discussing how to lower their sugar levels and sharing helpful advise. What was your physicians response to the change in your level?

Hi, @loaks I too welcome you to Connect. I have type 2 diabetes, diet controlled. @dorisena has some great advice there, she deals with this more than I do, my diabetes seems to be pretty mild. It really improved with a weight loss, which is pretty typical. Did you find that helped with you?
As dorisena commented, exercise is important too and I try hard to get a good amount in daily which has been harder now that we are self-isolating, but there are many excellent exercise videos on Youtube. If you are over 50 there are really good ones by

I generally alternate my breakfasts between plain yogurt with granola and berries added to it - there are some low carb granolas out there but you do need to check the nutrition info which I always do. The other breakfasts I have are oatmeal, with some chopped walnuts and berries added to it, and a couple of times a week I have an egg with cheese and a low-carb English muffin. Fiberone makes some decent ones. There is another brand also but they get very hard in the toaster.
I almost always have a salad for lunch and for dinner meat or fish and vegetables or salad.
I do manage to squeeze in some treats like dark chocolate but I try to keep most of the treats low carb.
Fruit is great but it does tend to be high in carbs so you do need to keep an eye on the amount of it that you eat.
I hope some of this will be helpful to you. Please feel free always to ask questions.
