Let’s apply some common sense to this.

If you died after a lifetime consumpution of 200 cans of soda, most Americans wouldn’t make it past age 14. That’s clearly not the answer.

If you died after 200 cans of soda in a month, well, most of the loyal readers here might not have made it past age 30. It’s painfully easy to drink 6 cans daily, especially if you’re trying to stay awake to finish a project. Conversely, it’s about 142 cups of coffee for me. That’s under 5 per day. I can drink more than that with few side effects. It’s not monthly.

Weekly? That’s just a stupid measurement.

Daily? That’s actually believable. If you managed to ingest that much caffeine in one day, you won’t be feeling so hot. In fact you may be in serious trouble. Not everyone’s liver works at the same speed, and some people have reported feeling the effects of caffeine for a full 12 hours – for most people this is more like 4-5 hours.

Here’s the answer: IT’S HOW MUCH YOU HAVE TO HAVE IN YOUR SYSTEM AT ONE TIME.

Yes, it means that it’s practically impossible to kill yourself with caffeine. Practically. Don’t actually try it! After 1 gram, you’ll be a sad panda. If you manage to even challenge the number, you’ll be a schizophrenic, crazed panda, or a passed out panda. And if you’re passed out, you might get your wallet stolen.
