A handful of walnuts or almond nuts if you have a small apple or pear or maybe berries.

Proteins: Meat, 3 fried eggs keeps sugar level stable all night and half a day.

my night snack consist of a bowl of cereal, puffed wheat or cherrios, or a toast with pb. I do not know why but I feel I need to eat before going to bed, I wish I could do without , as I am sure that is why my sugar is higher in the morning than any other time in the day.

Well if your BS are in normal range.I have a SF jello or a small glass of milk 1% or two celery stalks with PB and water...try to stay away from fruits with sugar like bannanas or oranages,. 🍉 if must have fruit keep it berries may 4 to 5. I make me a mini chessecake muffins...no coffee with cream if you need coffee add heavy whipping cream no carbs will not spike BS or just plain old BLK cup of joe.I hope these will help.
But please check BS...

I eat a few Graham Crackers. It works for me.
