I do remember these cool juice pouches I'd poke with a straw as a kid. I'd walk around with a bandolier full of them. Or maybe I'd snack on bananas throughout the day.

Actually, before taking steps to saturate myself at whatever level brings me no measurable willpower-deficiency, I'd investigate whether there's a possible training effect to enduring subjectively harder rigors while under the low-glucose condition. Plenty of people regularly don't eat at all until the evening and don't report feeling horrible after adjusting.

In other words, will I become dependent on my glucose-drip (constant snacking) so that I'm worse off if it's interrupted than if I'd never heard of this theory?

Even if I would become dependent with regular use, I'd still employ it at key moments in my life.
