How much caffeine is too much?

The Atlantic tries to figure out how much caffeine is unhealthy to put in you body. Yes, it’s about coffee. The number 400 mg is thrown around as a limit:

Four hundred milligrams amounts to around four cups of coffee in the old-style sense of the phrase, an eight-ounce mug in a diner. It’s more like one Starbucks venti.

If this was the case, almost everyone in Sweden is overdosing caffeine on a daily basis. Granted, the piece also states that more research is needed and that it’s most likely individual.

Personally I feel I’ve had enough coffee when I’m starting to feel sick.
