“Strong evidence shows that consumption of coffee within the moderate range (3 to 5 cups per day or up to 400 milligrams per day caffeine) is not associated with increased long-term health risks among healthy individuals.”
Some googling suggests that (regular) Coke has about 34mg of caffeine in a 12oz, so that makes around 280mg of caffeine a day. Perhaps he is abnormally susceptible of caffeine? or maybe was drinking “Coke” like a southerner, where it could be almost any carbonated drink?
