How much caffeine would KILL you??

This can greatly vary by person, but it generally takes a very very very large amount of caffeine alone to kill a person. Since large doses of caffeine can raise a persons heart rate, if there are pre-existing medical conditions this can be a problem. Otherwise if you stay within the 400mg/day of caffeine, the average healthy adult should be fine.

However keep in mind many caffeinated drinks have lots of calories and lots of sugar in them. The "other stuff" in these drinks is often more a problem than the caffeine alone.

So enjoy your caffeine in moderation, and you should be fine :)
If you need more official health advice about caffeine, please refer to the Mayo Clinic or the US Gov Report on caffeine.
