Although preceded by a reputation of careless carrier jets, a caffeine crash is incurred when having previously ingested caffeine in large amounts over several hours or days. The individual/lab rat may experience sudden fatigue, followed by excruciating alertness. Early symptoms are blank stares, babbling, swatting invisible moths, paranoia, standing on one's head and the looming notion that something is terribly wrong. At this point it is too late, a caffeine crash is impending. Complications arising from this condition may include insomnia, burn out, weakened bladder, drymouth, purple spots, green spots, orange spots, and rainbow spots.
