| Your liver reacts to many inputs...one could be blood glucose levels resulting from eating something. IE, the "body" says "Hey liver, we got some food from something dude ate, don't worry about injecting any of your stored glucose--we're good right now." ON the other hand, maybe when you skip a meal at waking, your "body" says "Hey liver, need some juice--hit me!" and your liver obliges.
Some Type 2's and Type 1's here get around these things by eating something fatty/protein laden like peanut butter at bedtime...it breaks down slowly, and it makes the body send the message that "all is well" long enough that the liver holds on releasing its glucose. I have also read some Type 2's taking a shot of Gin or Vodka at bedtime, because alcohol can have a suppressive effect on liver glucose release.
NOW...In your case...I'd be interested to see what happens to your sugars all morning with ZERO breakfast. Does it keep rising? Would it have still dropped to 97 without breakfast? Etc.
