That caffeine intake was daily.

My poison of choice was Rockstar Pure Zero - Mango Orange Passion Fruit. They originally launched with 160 mg per can, but bumped it to 240 mg. http://www.caffeineinformer.com/caffeine-content/rockstar-pu...

Like I said, not one of my brighter moments - I was just willing to do whatever it took to launch. In hindsight, not worth it at all.

As someone who experiments with nootropics, I highly recommend modafinil over caffeine for sprints like that (up to 36 hours of wakefulness at a time, no jittery feeling, etc). You should not do it for any appreciable amount of time though. See https://reddit.com/r/nootropics for more info.

Modafinil is much more expensive, harder to get, and not everybody responds to it.
