Not everyone is the same. I have heard of drug addicts who could only drop heroin by replacing it with massive amounts of highly-caffeinated energy drinks, in quantities that would be objectively bad for most regular folks.

I only managed to drop drinking a shit tonne of Red Bull once I started Ritalin.

Wow that explains a friend’s monster energy intake

Yeah I know several people who tell me the same like you... Again not proper science but it seems that caffeine tolerance and metabolism is quite different from person to person.
