So... is the view that morning blood sugar being high comes from (unless you've been raiding the fridge late at night) gluconeogenesis - or just the stores in the liver rather than feeding on ones own protein?

If gluconeogenesis were the problem, something you wanted to dissuade, it would be helpful to know what prompts and inhibits gluconeogenesis.

To that end, I did find this:

In vitro effect of caffeine on some aspects of nitrogen metabolism in isolated rat hepatocytes... We have found that, whereas it has a small effect on urea synthesis and on the levels of the cofactors and intermediates, it decreases the levels of several amino acids, the gluconeogenesis and the redox state...
