caffeine

An essential vitamin, without which one suffers from headaches, depression, sudden violent anger, sluggishness, muddled thinking, and crankiness.

I once went 10 months without vitamin C and only suffered a mild bout with scurvy and tooth loss...I went 24 hours without caffeine and that's why I'm doing life without parole.
