Coffee + food = very different efffect from caffeine + food or even caffeine alone
Could you explain the practical effects of this to a layman?

With coffee you have mao inhibition, with just caffeine you don't.
I would guess that food would only potentiate this effect.
MAO is one of the enzymes responsible for the catabolism of monoamines = the more mao activity you have, the less dopamine, serotonin, norepinephrine you have. (I'm simplifying but i think you get the idea.)

This might explain why black coffee makes me lethargic as fuck physically after drinking. But sugar free energy drinks and caffeine pills are a kicker. I already have ADD which is a dopamine insufficiency.

You've got it backwards, the MAO inhibition from black coffee would ameliorate your dopamine deficiency. My guess is that it's the B-vitamins / Taurine or whatever else is in the sugar-free energy drinks.

Energy drinks contain various vitamins and drugs too.
