That's not to say there aren't close calls, especially in children. A girl in Ohio suffered seizures, heart problems and fluid in her lungs after she ate her mom's diet pills, containing 2 to 3 grams of caffeine (the equivalent of eight or 12 cans of Monster). She was transported by helicopter to the pediatric hospital in Columbus and survived, despite the high dose and her age: just a year old. In another instance, a 16-year-old boy in Toronto ingested something like 6 or 8 grams of caffeine (25 to 33 Monsters) via 30 or 35 pills called "pink hearts." He suffered chest pain, elevated blood sugar and irregular heartbeat, but was treated and survived. The physicians who published on the case noted: "On examination, he was alert, oriented, nervous, agitated and irritable"--exactly how you'd imagine a teenager on way too much caffeine.
