Death by Caffeine

How much Dr. Pepper will it take to kill you? Will you fare any better with Mr. Pibb?

Thanks to Death by Caffeine, I learned that I can only drink 266 cans of Dr. Pepper before the caffeine does me in. I could drink 273 cans of Mr. Pibb before knocking off. And my favorite, hot cocoa, will allow 780 cups before kicking the bucket. Now hopefully I don't lose count between 560 and 600 again....
