Are you sure it's the caffeine and not another substance in coffee?

why does it work with caffeine?

Look into the CYP1A2 gene (which codes for the enzyme by the same name, which is responsible for metabolizing caffeine). People are different (which is why there are limits to large studies of general population) - for some people, caffeine might be helpful while for others it might be harmful.

caffeine is more likely the culprit

Must be the addictiveness of caffeine creeping in :-(

Sure, but your case is 1. There are many people addicted to caffeine, and it did affect their sleep and mind. (Writing this sipping my mandatory coffee :)

Does caffeine intake nullify this effect?

Or loads of caffeine to the point it is questionable?

You’re forgetting that caffeine is a drug.
