Hi
@RayCox - could you just expand a bit - what do you mean by too low?
for any meal, and particularly first thing in the morning, that requires insulin to process, you would expect some form of the classic curve...
I don't mean to insinuate that what you are describing is a "spike" - that's just the image, but the point being that anything like this will tend to result in a lower level of glucose than what you start with around about the time you are measuring, before it recovers again.
I think this is what you are seeing.
You would have to be using a CGM to get a better insight though.
