Can you overdose on coffee

Coffee has different effects on different people but an overdose of coffee can lead to heart palpitations, hypertension and even death.

In my case six to seven drip filter coffees per day led to irritability, hypertension, a feeling of panic which culminated in my passing out while driving home from work.

The passing out was probably a seizure caused by the coffee since had been having feelings of Deja-vu and unreality all day as well as a feeling of panic.

Fortunately I wasn't hurt but my car was a write-off. It could have killed me.
