Some effects of caffeine : increased mental alertness, restlessness, nervousness, insomnia, dilation of the bronchioles, increased blood pressure, and increased renal function. Increased renal function means you pee more.
Mike, caffeine causes cardiac arrhythmias, which cause quivering. If the heart was able to coordinate the rhythm, it could beat at that speed and not explode.
At about 2mg/kg load, caffeine will induce nausea, vomiting, and muscle spasms.
Amp has 77mg/8oz. If DJ drank 6 cans, that would be 50.4oz of Amp, 3,881mg of caffeine. I don't think DJ weighs 887 lbs, so that would induce "BAD THINGS" in him,
if ingested at the same time. The liver will have processed most of the caffeine out of the blood about 3 hours after ingestion.
Amp also happens to be my drink of choice to stay awake on the road. Works rather well. Should have used it when I pulled a 54 hour day before the VCU regional in 2002, then tried to drive the 2.5 hours there.
