Ok I have to be honest and say when I first heard this story I laughed and said 7 double expresso's is nothing.
A teenager was taken to hospital after overdosing on espresso coffee.
Jasmine Willis, 17, developed a fever and began hyperventilating after drinking seven double espressos while working at her family's sandwich shop.
Now to be fair it was a teenage girl who 17 and shes maybe not use to drinking a lot of coffee anyway. But I got to say when I worked in Starbucks in Victoria. I use to drink about 4-5 double expresso's a shift. But then again I was also drinking about 4-6 cans of redbull on a weekend too.
I found this great site about caffeine via DL.TV a while back. Death by Caffeine allows you to put in your current weight and it will work out how much cups of coffee, tea, insert name of energy drink here it will take to kill you. This might sound all in bad taste following this teenagers near death experience but you got to look on the light side. Oh and drink less caffeine.
Some slighly shocking findings.
It would take over 200 cans of redbull to kill me by caffeine alone but only 150 expresso's. Actually a double shot of Starbucks Coffee has double the caffeine of Redbull when you look at it per ounce and a expresso 5 times more.
At the top end of the list is Fixx Energy which has 500mg (85ml per 100ml) of caffeine in a bottle, which just beats a Starbucks Grande Coffee which has 372mg but 79mg per 100ml. But if your deadly serious about your caffeine in take you need to look at the pills and mints. No-Doz, Maximum Strength and Dexatrim has 200mg per pill! No wonder I was still very wired at 8am in the morning after going out clubbing when I was younger. Luckly I never experienced what Jasmine did.
