A lethal dose of caffeine is upward of 10 grams. Rough calculations place Andrew's Frap at about 4.5 grams, but the man was not about to drink it all in one sitting. He claims that he "drank about 30 percent the first day." Though he couldn't finish in one sitting, he didn't toss the rest out either. To the Twitter naysayers out there, he clarified, "Still working on it . . . I don't waste coffee."
